Vertical lines when playing MPEG-2 videos

[pacifist]

Okay, they aren't visible black lines, but it is like every 16 lines the picture is slightly offset..this is especially visible on fullscreen mode, and only happens when playing m2v or m2p MPEG-2 files..

Also, the keyboard has just stopped working in BS Player, so I can't use + and - in full-screen, or even get to fullscreen without using the mouse...
