16th June 2014: 752BD(CU)-18-0515

1. Fixed a bug in calculating acoustic propagation delay from the "Speaker Distance" parameters of the "Speaker Configuration" setting.

2. Improved Gapless Playback (via USB only) performance. Resolved issues such as the second track playing twice before moving to the third track.

3. Resolved an issue of “Reset Factory Defaults” not erasing the user account details for the Youtube application.

4. Resolved an "A/V Sync" related issue where the A/V Sync data was not be automatically applied to the Coaxial and Optical digital audio outputs after the player was powered on.

5. Improved the file sorting algorithm for the media center (the Music, Photo and Movie options on the Home Menu). The player can automatically detect numbers located at the beginning or end of the filenames and sort the files by the numeric value. Albums with numbered tracks will play in the proper order.

6. Added the timing adjustment for external subtitles. This can be accessed from the "Option" menu -> "Subtitle Adj." -> "Sync." when playing movies from a USB flash drive or external hard drive.

7. General disc compatibility improvements based on recent and upcoming Blu-ray releases as well as user-submitted disc samples.

All features and improvements of the previous firmware are also included in this version.

Note: playback of BDMV folders/files, ISO files and SACD-R is not supported due to copy protection laws.

 

14th March 2014: 752BD(CU)-17-0304

1. Improved Gapless Playback (via USB only) performance and added Gapless Playback (via USB only) support for FLAC files.

2. Resolved several issues involving Gapless Player (via USB only), such as the track title not getting refreshed in the Now Playing interface, and the player becoming unresponsive when trying to access a disc in the tray without stopping the currently ongoing Gapless Playback.

3. Resolved an issue with Gapless Playback (via USB only) with several customer-encoded WAV files. It was caused by an additional “List” information segment presented in the WAV file Header, and we have added support for this segment so that Gapless Playback now functions properly with these files (via USB only).

4. Improved HDMI handshake performance for the HDMI input ports.

5. Resolved a compatibility issue with the HDMI 2.0 input port on some Panasonic 4K TVs. For example, the #4 HDMI port on TV model TC-L65WT600. This port contains additional Extended Display Identification Data (VSDB) blocks which caused our player to switch to DVI output mode and discard the audio packages, so there would be no audio from the TV speakers. We added support for these specific VSDB blocks and resolved the no audio issue.

6. Resolved a compatibility issue 752BD HDMI 1 Output to the McIntosh MX150/151 AV Processors. Users reported no audio when using this combination, so we added special instructions for these A/V processors in the HDMI handshake process. We highly recommend that you contact McIntosh Technical Support to upgrade your MX150/151 firmware to the latest version.

7. Resolved the Wi-Fi connection failure with access points or routers using WEP security. This error was introduced by 15-1204 firmware and this version corrects it.

8. Resolved an audio truncation issue occurring with several DVD-Audio discs. Customers reported that the first note or two was cut off between track changes, and when the PREV button was used to restart the current track. Sample discs included "Queen: A Night At The Opera", "Buena Vista Social Club", "Beatles: Love" and "R.E.M.: New Adventures in Hi-Fi". This error was introduced by 15-1204 firmware and this version corrects it.

9. Resolved the playback failure with certain customer-encoded audio files in WAV, FLAC and AIFF formats. Symptoms included files being skipped, files being played with static noise, and files causing the player to freeze. The 15-1204 firmware adds more support to meta data tags in these files but encounters this problem if the meta data tags are in non-standard location. This version further improves the support for meta data tags and corrects the problem.

10. Resolved an audio dropout issue occurring with "Monsters University (BD, 2013)", related to its Dolby TrueHD 5.1 and 7.1 audio tracks when the player's HDMI Audio Format was set to Bitstream. We worked with Dolby and our decoder chip maker to address this type of audio dropouts.

11. Added 24 Hz support for customer-encoded video files in 480P24 and 720P24 formats. The original frame rate can be preserved when upscaling the content to 1080p, e.g., when Resolution is set to 1080P, the 720P23.976 content is output as 1080P23.976, and 720P24 is output as 1080P24. Previously, these formats were frame-rate converted to 60 Hz.

12. Added an "INSTANT REPLAY" function to video playback. If the customer presses the AB REPLAY button twice (two presses within 1 second), video playback will be automatically rewound 10 seconds.

13. Resolved a HDMI handshake failure when the 752BD's HDMI Output is connected to an A/V receiver, while the same receiver's HDMI output is fed back to the 752BD's HDMI input. We added special handling for this kind of "loop" connection and resolved the handshake failure. However, we highly recommend that you do not use this "loop chain" connection since it might cause unexpected HDMI handshake or CEC results, or even cause electrical damage.

14. Added indications on the front panel and TV screen for DSD file (.dsf, .dff) playback. If a DSD stream is output through HDMI, the "SACD" icon on the front panel will be lit and the TV screen will show the “Track Type” as "DSD". If a PCM stream is output, then both the "SACD" and "PCM" icons on the front panel will be lit, and the TV screen will show the “Track Type” as "DSD to PCM". This way, the customer will know whether a DSD-to-PCM conversion is happening in the player.

15. General disc compatibility improvements based on recent and upcoming Blu-ray releases as well as user-submitted disc samples.

All features and improvements of previous firmware updates are also included in this latest version.

Note: playback of BDMV folders/files, ISO files and SACD-R is not supported due to copy protection laws.

 

16th January 2014: 752BD(CU)-14-0719

1. Added the "Power On Input" selection which allows the customer to decide which input source should be used when the player powers on. This selection is available at the Setup Menu -> Playback Setup.

2. Added the “4Kx2K Output” selection to Setup Menu -> Video Setup with two settings: “Auto” and “Forced”. The “Auto” setting will upscale 24 Hz content to 4K if the connected display supports a 4K input. The “Forced” setting will output a 4K signal regardless of whether or not the player detects a 4K display and irrespective of the original source format.

3. Added the "Auto" mode when choosing the SACD output audio format. This mode is available at the Setup Menu -> Audio Format Setup -> SACD Output.

4. Added support for automatic file and folder sorting when accessing SMB servers. The files and folders are now sorted in alphabetic order.

5. Added support for MKV files with PGS subtitles.

6. Added Zoom functionality to video content sent through the HDMI IN ports.

7. Improved support for CUE playlists. Now, a single CUE file can point to multiple music files in the same folder.

8. Resolved a playback issue with several DVD-Audio discs. Customers reported that some DVD-Audio discs would play for a few seconds then the player was locked up, and all you heard was white noise. Samples include “Elvis: 30 #1 Hits”, “Bruckner: Symphony No. 7”, “Dream Theater”, “Nightwish: Once”, as well as discs self-authorized using “HD-Audio Solo Ultra” program.

9. Resolved a frame rate decoding error for 24 Hz video files. Customers reported that many MKV, M2TS and TS files which were encoded as 23.976 Hz were decoded as 29.970 Hz. This issue has been resolved.

10. Resolved a compatibility issue with some DVD/BD blank discs. Customers reported that their self-burnt DVD or BD discs failed to load and play on the players. Samples include Verbatim DVD+R DL 8.5G and BD-R DL 50GB blank discs. This firmware upgraded the software driver for the disc loader and resolved this issue.

11. Resolved a compatibility issue with JRiver Media Center software. Customers reported they could no longer see the JRiver's DLNA server in the list of My Network. This issue has been resolved in the official release.

12. Resolved a channel mapping error in the DSD file playback, Customers reported that if they set the "Stereo Signal" to "Front Left/Right", switched off the player then switched it on again, and played 2-channel DSD files from external storage, the Front Left channel sound could also be heard from the Surround Right output. This issue has been resolved in the release.

13. General disc compatibility improvements based on recent and upcoming Blu-ray releases as well as user-submitted disc samples, sample title includes "The Longest Day (Blu-ray, 2012)".

 

21st August 2013: 752BD(CU)-14-0719

Features of the this update (version 752BD(CU)-14-0719) include;

1.     Added support for ALAC (Apple Lossless Audio CODEC) playback.

2.     Added support for DSD audio (2.8MHz, 64FS) playback. (5.6MHz, 128FS DSD not supported)

3.     Improved the Audio/Video synchronization when streaming from some cable TV boxes connected to the HDMI IN port (Front and Back). Customers have reported that with normal TV playback, if there is any change in the content audio format (for example, from Dolby Digital 5.1 to Dolby Digital 2.0), the audio/video outputs could become out-of-sync. This issue has been significantly improved upon in this firmware.

4.     Resolved an issue where the player would slow down, and sometimes freeze entirely, when navigating files on some connected USB hard drives. Several customers have reported this issue with their Western Digital external hard drives, and they had to power down the player then power it back on to restore its performance. This issue has been resolved.

5.     Resolved an issue where a loud popping noise could be heard at the end of playing some WAV, MP3 and DSD music tracks.

6.     Resolved an issue where accepting a cable television signal through the HDMI inputs might result in a black screen. Customers reported that if they kept changing the TV channels using the cable remote, sometimes they would only see a black screen on the TV, even though the audio was still ok. In order to restore the video, they had to force a HDMI handshake (changing the input source, hot-plug the HDMI cable, etc.).

7. Improved CUE file support. Now CUE files can contain non-English characters in UTF-8 encoding.

8. Added support for briefly displaying the current audio information on the player's front panel when switching audio tracks. The audio information is displayed as "Language, Sample rate, Number of channels", such as "ENG 192/5.1". If no language information is available, it will be displayed as "AUD, Sample rate, Number of channels".

9. Added support for directly switching the input source by pressing the INPUT button followed by a numerical button, e.g., "1" for BLU-RAY PLAYER, "2" for HDMI/MHL-IN FRONT, etc.

10. General disc compatibility improvement based on recent and upcoming Blu-ray releases as well as user-submitted disc samples.

 

17th June 2013: 752BD(CU)-13-0604

Features of the this update (version 752BD(CU)-13-0604) include;

1.     Resolved the HDMI high bit-rate (HBR) audio loss issue with Yamaha RX-V673, V773, A820 and A1020 AV Receivers. Customers have reported that when sending DTS-HD Master Audio or Dolby TrueHD signals in "Bitstream" mode through HDMI to these Yamaha receivers, any signal interruption (resolution change, source selection, etc.) will cause the Yamaha to display "Audio Decoder OFF" on the front panel and produce no sound from the speakers.

2.     Added a feature that allows the adjustment of the audio delay time within the range of -100ms to +100ms. This can be set in "Setup Menu"->"Audio Processing" -> "A/V Sync", and the delayed time will be applied to all output terminals including HDMI 1 and 2, Coaxial, Optical, and 7.1 outputs (including the Stereo outputs of the 752BD).

3.     Improved compatibility with some cable TV boxes, especially from Motorola. Customers have reported that HDMI handshake failures (such as blank green screens, flickering images, and frequent audio drops) could happen when these TV boxes were connected to the HDMI IN port (Front and Back). This issue has been significantly improved in this firmware.

4.     Added support for CUE file playback. This function can be applied to music files on local storage and supported audio formats include FLAC, WAV, APE and MP3.

5.     Added a feature that allows the creation of playlists while accessing music files from local USB storage. When navigating these music files, pressing the OPTION button will bring up a menu with a prompt to either "Add to playlist" or "Goto playlist". The created playlist file is stored within the local USB storage, inside "CA_Media_Info/playlist".

6.     Added support for the AIFF audio format. (Standard AIFF files are supported. AIFF files with AIFF-C/sowt encoding generated by Mac OS X are not supported.)

7.     Added support for the ExFAT file system.

8.     Added additional Crossover Frequency selections (50, 70, 130, 140 and 160Hz) in "Setup Menu"->"Audio Processing"->"Crossover".

9.     Added a feature that allows the user to decide which mode (Auto, Film and Video) to use when performing video de-interlacing. This can be set in "Setup Menu"->"Video Setup" -> "HDMI Options"->"De-interlacing Mode".

10.   Added DMR Seek capability, so the user can drag the progress bar on the DMC side and adjust the media file playback progress on the player.

11.   Resolved a recently reported FLAC file playback issue. Some FLAC files made from the latest version of the EAC (Exact Audio Copy) software tool could not be played on the 752BD. This issue has been resolved.

12.   Resolved the brief audio pop issue found on the 7.1 and Stereo audio outputs. This popping noise could happen when the player is processing content from a television cable box (through the HDMI inputs), and when channels are switched on the cable box. This issue has been resolved.

13.   Improved the support for large capacity external hard drives. The maximum size for a single partition can be up to 16 TB when using GPT partition table and NTFS or ExFAT file system.

14.   Improved the digital audio compatibility with the Apple Airport Express (2nd Generation). Customers have reported that frequent audio dropouts were heard on 752BD's analogue audio outputs (both 7.1 and Stereo) when accepting a digital audio signal from the Airport Express 2's optical audio out. With this firmware, the audio dropouts have been eliminated or significantly reduced.

15.   Removed a limitation in "Audio Processing"->"Speaker Configuration", that turns off the SBL and SBR speakers automatically when the Center speaker is set to "Off". However, if the SL and the SR speakers are set to "Off", the SBL and the SBR speakers will still be muted.

16.   General disc compatibility improvement based on recent and upcoming Blu-ray releases as well as customer-submitted disc samples.

Note: playback of BDMV folders/files, ISO files and SACD-R is not supported due to copy protection laws.
