How to fix a damaged MKV file? Options

[RM]

Hello.

I am having problems with a movie file in MKV format. The movie length is 2 hr 18 minutes, however the VLC player (and others) stops playing it approximately at 1:44:50. But if I manually run the player and then rewind to 1:45:00, the movie plays fine from that point and to the end.

Also, I wanted to add an additional AC3 soundtrack to that movie. I was trying to use mkvmerge (through mmg), but it produces an incomplete file (sized 6.5 GB only, while the original size is 7.7 GB, and the additional track I am trying to add is 632 MB in size).

So obviously, there's a certain damaged fragment inside MKV file, which causes players to stop playback and mkvmerge to stop processing the file. The question is, how do I fix/remove that fragment? It would be OK even to lose a second or two of movie itself. But I have found no tools to check for and correct damaged parts inside MKV files, not even any tools for simply cutting out such parts.

Thanks in advance for any reply.

Thanks for the advice.
Unfortunately the torrent passes verification ("Force re-check" in Azureus) just fine.
So I guess the person who shared it already had the file corrupted.
This was on a small private tracker with few users, so the problem wasn't spotted quickly by anyone.
