in mediaportal configuration, you could specify use of ffdshow for playback of the video and audio streams
this should beat the merit hell around codecs
otherwise run gspot codec information appliance on the files and report what filters are active
what's in your system tray when you play the files (you should see ffwshow and haali splitter icons kicking in for mkv playback
standing back, what kind of video file is wrapped inside the mkv - mkv is a container for video and audio
the video and audio can be compressed by any number of different codecs, ffdshow has enough to decompress most, but not real or quicktime files
gspot would help that
i'd have expected h264/x264 and ac3 audio, but i might be wrong ! |
