- Fix: Mbaff & paff combination

- Fix: Multiple multithreading issues
- Fix: Directshow: Changed property pages to IPropertyBag (internal change, the
only user visible effect is the page works from remote graphedit now)

and subtitles to dsmux (requires Gabest's Subtitle Source filter). Added an option to
disable error messages, the splitter will silently fail on invalid/unsupported files.
Thumbnails are now extracted in a separate process, so buggy codecs should no
longer affect the host application.
[Matroska] Much improved mkv2vfr utility now handles AVC video and correctly writes
AVI files larger than 2GB, it is now included in the splitter package.
[OGM] Added support for a couple of other ancient versions of the format.

records. Added a simple MP4 muxer. [General] Muxer improvements, video renderer bugfixes
and improvements.
