I will (try) to aggregate pending problems/bugs with the FW6.3.12 here. Items fixed with FW6.3.2 were removed. Also removed some mere "nuisance" type of problems which are considered inconveniences. The focus is on the more serious items and features directly claimed to be included. Will keep updating it with any new FW released for all models. Things confirmed as fixed will be marked green with the actual FW release and be removed with the next FW update available for all models. Assigned numbers will be kept. Please don't forget to report items you think have been fixed too! Hot items are displayed in red. These have a big impact at least for the users relying on a bugged existing feature which must have been introduced later. Not for new features under development or things which never worked correctly before. Things not working as one likes or feature requests are not to be included. Just matters not working as advertised/claimed. Problems must be repeatable and confirmed by several persons. They also should implicitly apply to all RTD1619DR based models and any TV/AMP being used (excluding all DV and VS10 related issues) unless stated specifically. Use my Z9X purely for validation being a clean machine with no add-ons installed. 1. BD menu processing: BD Menu processing works mostly (my guess above 95%). The nasty thing is that BD Menu's mostly fail (getting stuck) when you need/want them to work most being with multi-cut version BD's, with Multi-Episode/Multi-Movie BD's/BD Pure Audio albums as you need the menu for these to select the desired playlist/track. Problems with BD-Menu are very common also if the menu is multi-language which is more often the case with recent movies including UHD. The workaround is just starting default longest track playback without BD menu and then going to the BD Menu option for direct track selection. That will mostly do the trick to still getting the desired track to play. Some BD's you can start from "the chapters selection" as a workaround rather than "play movie" if it returns back to the main menu selecting play. 2. DVD menu and playback processing DVD-Video menu processing has multiple flaws including turning subtitles off and these are there since the beginning for all Zidoo player models and generations. It just never got enough attention. The nasty thing is that DVD Menu's are always processed and can't be bypassed. In almost all cases one can still get the movie to play and it is just annoying. DVD-Audio Discs (with MLP HD Audio in the AUDIO_TS folder) is not supported and never will work without perfect menu processing as there are many ways interactive menu's are being used with these discs for track and feature selection during actual playback. For that same reason DVD-Video compatibility for DVD-Audio discs does often not work either making playback totally impossible. 3. Music Player problems with mainly HD FLAC sources being 24-bit (88.2, 96, 176.8, 192) This with output set to play source formats up to 24-bit at 192 kHz and HDMI/SPDIF output set to RAW. MP runs into CPU limitations relative quick. Must be the way drivers are programmed. I can simulate this by doing a Filetransfer via SMB in the background. Also simple FLAC playback via the DAC may then show mentioned sound problems. Video Player seems to use far less resources as it plays fine even with SMB transfers in the background. 3a. DSD => PCM conversion with HDMI output is still 16-bit instead of 24-bit. Not being part of the problem reported it is excluded but considered a related flaw. DSD 64 outputs as PCM 176/16 bit via HDMI DSD 128 outputs as PCM 88/16 bit via HDMI DSD 256 outputs at PCM 44/16 bit via HDMI 4. Kino Lorber BD movies not finding the single subtitles included (mostly EN) When playing without menu the player reports no subtitles found. When playing with BD Menu though there is an option for toggling subtitles ON/OFF which works then just fine. This could be Realtek SDK related? All movies of Kino Lorber have this problem. KL is famous for releasing large quantities of restored classic movies. https://www.klstudioclassics.com/ 9. MP does not support UTF-8 when reading tag files. Only English is displayed normally. National symbols (Russian for example) is displayed as Chinese characters. 10. MP does not play all DTS-CD's correctly About 1%-2% of discs just play in 2CH and a sporadic number just produce noise. All play fine using my OPPO. 12. 3D not triggered when playing 3D-BD ISO with Menu. - When you only "Play video", output in 3D is triggered, and playback is smooth - But when you "Play with Blu-ray menu", 3D is not triggered and movie plays only in 2D 13. Playing a movie with a DTS-HD track adds 2-channels in info. MA 5.1 soundtrack, displays as DTS-HD 7.1 etc. DTS-HD MA 1.0 (so in mono) as info gives DTS-HD 3.0. Other ones in DTS or Dolby Digital are ok. 14. SMB performance not optimal. Several reports of problems with above all heavy network load movies. Problem can be reproduced playing UHD ISO's using SMB not happening via USB/SATA. Using the same files played on other brand players with the same SMB server and LAN do work flawless and even more curious also UHD MKV play fine too. Rollback to 6.0.45 and they are gone is reported. This seems partially fixed/improved but still many claiming not as good as on previous generation SOC's. Moving from SMB => NFS seems to solve the problem at least for some. QNAP SMB Servers seem to suffer from this the most. 15. Netflix giving an 1044 error when play is started. Netflix applied apparently a ban on actual movie playback with the Zidoo player producing this error when tried. It seems Dune & Himedia players now got that same Netflix treatment too, so unlikely to be fixed. Instead the Netflix APP is expected to be removed from FW distributions. 21. Roon certification problem Roon seems to be compatible as claimed but Roon also validates certification of the player using it which seems to be not complied with yet. 22. No play with no error when trying to play SACD MCH only DSF/DFF/ISO track/album. Tracks will be just skipped and no action taken which is extremely confusing as it is impossible to see if it is 2CH or MCH. It should pop-up with "Unsupported format" or something similar. 23. UHD3000 plays 2.0 PCM 96/24 or DD True HD in slowspeed via DAC when a e.g. a Music BD is played. Does not happen with HDMI output and neither playing the DTS MA HD tracks. MP6 plays PCM 96/24 and other 24-bit PCM formats correctly. Please don't start discussions here, do that in the FW release topic itself or start a dedicated topic for it. Just mention items you think that should be on the list. I will aggregate them next after reading the relevant material and/or reproducing myself.
