I have my NCED video in MKV format, then I used MKVCleaver to extract the video portion and convert to .avi format. I checked that it plays properly in various media players (the .avi file), but it is not being opened properly in avidemux. It detects 0 frames and wont even play the avi file. How should I go about converting my mkv file? Any help would be appreciated, thanks in advance.
