Thats a good question. What program are you trying to play the MKV file from? Like VLC, Media Player classic, ect. Cause it might just be a codec issue. I know when I downloaded a MKV file one time it was badly done. Or was a bad download. So I used VLC and it would play a little bit here and there. So I stopped using torrents to find my MKV files and used good old downloads. That seemed to help my issue greatly.
But if you use say like "mkvtoolnix" which is a program that has tools to create, alter and inspect Matroska files(mkv). So if you use it and it doesnt recognize the file. Then you know its either a corrupted download or a fake.
But if your looking for a codec for MKV myself I have VLC player with the lazy man’s mkv pack and the mastroka pack v1.1.1. Which now lets me see subtitles and all that great stuff.
Players:
VLC Media player
Media Player Classic
Codec
lazy man’s mkv
- Well thats all I can think of right off the top of my head. But you might be just getting bad MKV files. If thats teh case VLC player should play it even if the files bad cause it will skip over headers. So if its fake or even just random bits of that just means theres nothing to play.
-I doubt it but it but I did have a ton of codecs on my pc long time ago and they did conflect with each other. But then again thats just a last ditch effort. XD
