Hi! I was wondering if I can find some help here regarding my mkv file. I've played numerous mkv's before, but I've come across some that have shadows, lines or some uneven colors in the picture. But in some computers, this problem doesn't seem to happen. I'm using an Intel Core 2 Quad CPU Q9300 @ 2.50Ghz with 2Gb RAM, windows XP SP3. I also have K-Lite Codec installed with Media Player Classic.

what do you guys think could be the problem?
Thank you very much!
