Changelog for Beta 6 Bugfixes:
* Important security fix: Buffer overflow vulnerability was fixed
* Fixes to ffdshow's remote API
* GDI resource leak fix
* Subtitle fixes:
*
o Fixed missing character at the end of line with non-UTF8 encoding in embedded subtitles
o When activating SSA tags within SRT subs, default placement (with no tag) was not correct
o Subtitle stability fix for random crashes
* Workaround for crashes in applications that use the Windows Media Player SDK
* Wrong color fix for Fraps v5
* The Grab filter was producing a black right border when saving PNG images having a width which was not a multiple of 16
* OSD / Info & CPU: Show correct value in "Movie FPS"
* Crash due to a language file size limit was fixed
New/updated features:
* Added support for E-AC3 decoding (Dolby Digital Plus)
* Added support for DTS-HD decoding (core DTS only)

* New deinterlacer: yadif (Yet Another DeInterlacing Filter)
* Updated libavcodec with the latest code from the FFmpeg project
* Volume normalization:
*
o One-pass normalization added. This mode is used to reach the highest possible loudness with minimum of possible artifacts
o Improved normalization, the probability of clipping has been decreased
* Added support for S/PDIF sample rates other than 48kHz: Pass-through of 44.1kHz AC3/DTS streams plays back correctly now
* Dynamic range compression level for AC3 and E-AC3 sources can now be set between 0 and 100%
* AC3/DTS pass-through settings are now based on presets
* DVD playback support by libavcodec
* Tweaked compatibility list reporting: Executable names that are not yet in the default whitelist/blacklist are now reported only
* Unicode support for FFDShowRemoteAPI

*
o Buffer limit increased from 256 to 2048 characters
o HTML encoding support similar to SRT files
o Added SSA support for OSD and combobox to select the format (HTML/SSA)
* SRT files with tags support: SSA tags support in SRT files and HTML tags support in SSA files
* Improved compatibility with certain MPEG2 Transport / Program Stream demultiplexers (e.g. DVBSource, Elecard) for files that contain H.264 video
* Support H.264 digital television playback in DVBViewer
* Improved H.264 seeking
* Added an option to deinterlace only frames flagged as "interlaced"
* Enhanced interlacing options allow to choose the method (auto, weave, bob) as well as the field order (auto, top field, bottom field)
* Color space conversion: Added option "Force progressive" and "Force interlace"
* Flag telecined frames as progressive (libmpeg2)
* H.264: Correct field order, interlace/progressive flags are decoded[/more]

http://downloads.sourceforge.net/ffdshow-tryout/ffdshow_beta6_rev2527_20081219.exe В новой версии добавили, в т.ч., декодирование Dolby TrueHD, теперь непонятно: а какой контейнер и сплиттер использовать? MKVtoolnix муксить TrueHD в MKV не умеет, TSmuxeR муксит только, если есть AC3 ядро (только его и муксит?). Пробовал в MPC-HC скормить .thd трек параллельно с видеофайлом - не воспроизвёл.
, помню из-за этой хрени мучался с Xvid-ом, и нигде не было упоминания что чего-то не хватает. странно только, что настройки работают.
