Most likely, it's a problem with that video's not with the players. If you don't believe that, copy a few to your USB-stick and try the same on another PC.
If so, just don't do it.
A few months ago I started having a problem with all my video players. Windows Media, Quicktime, Realaudio, etc. On certain vids, if I try and use the seek bar, or fastforward/rewind buttons, the player crashes. It plays fine, but 99 percent of the time crashes when I try and seek. This is usually vids that I get from sites like rapidshare. I noticed one vid I had I tried to watch today, which worked fine when I got it, crashed. It was from a torrent site I think.
The only possible info. I got, is once when I sent an error report, the message indicated a possible codex problem, and that they are aware of it and trying to fix it. Well, it's been months.... I'm not sure how accurate the report was.
I use Windows xp serv pack 3.
If you need any specific info. about my system let me know what, and I post if I know how to find it. Thanks.
