Hi, im here today because i recently started having a problem on playing video, when i try to play some video in any player like mpc and zoom player, it appears to me some strange points in random positions on the video (it depends on the video), generaly are 3 lines aligned, something like this:

But not in black of course, when i try to open it in a software called "aegisub" wich is like a free version of after effects, nothing like this appears to me on the video, i think it is from matroska (i use cccp btw), because aegisub only needs to open ffdshow audio...

The following problem already happened to me with some mkvs and avis.

Anyone knows what can cause the problem?

Thanks...
