Only thing matroska lacks is hardware support .... (Score 1)

... and we are already working on this, together with a very well respected company doing MPEG4 players. Dont expect it in the near future though, current decoder chips like the SIGMA EM 8550 are not powerful enough to decode MPEG4 video and Vorbis audio at the same time, and this is the most used profile in matroska files, followed by MPEG4 video and AAC audio ( together with SRT or SSA subs ) and RealVideo9 and Vorbis audio. Soon we will launch the latest features for matroska files, that will be the ability to store DVD subtitles ( vobsub's ) in MKV without the need to OCR them, and then MPEG2 video is the next on the list, so you can mix your SVCD video with Vorbis audio tracks :P ...
