Diagnosing video file integrity?

[gaikokujinkyofusho]

Hi, I have some .mkv files (in this case) that I am positive should be slightly corrupted (got via torrents and some didn’t completely finish downloading [stopped being seeded before I finished]). The puzzler is that they *seem* to be fine, usually I just play a file with wmp and it balks if there is even a small error but with mkv files most player that will play mkv are pretty tolerant (KMP, VLC, etc) so I can’t be sure. I did find Meteorite but it seems to be more geared for fixing files that are known to be corrupt, regardless it kept crashing on my system (win7 64b). Any tools that might be of help would really be appreciated!!

Cheers,
