After days of normal work (computer is running constantly), videos were corrupted, see attached screenshot (pattern of corruption was same on all videos).
Restarting xorg fixed problem, however this didn't happen with previous drivers. The problem seems to be reproducible only when you leave computer for days, but it occured once, since it was running from nvidia driver update.

Bug report included, however I forgot to run it when problem was actually present.

EDIT: mplayer is using xv.
