Fwiw, I've seen similar problems with the intel driver
until recently. Xv didn't work when a compositor was
active. Are you using a compositing window manager?
This has improved with xf86-video-intel-2.2.0 -- Xv
did work, but there were performance problems. I'm
currently testing 2.2.1, the performance seems to have
improved.
So I'd blame the xf86-video-via driver. Unfortunately
there doesn't seem to be much development...

Is there some specific video codec support in the via graphics which
DRM could make use of?
Otherwise, I'd suggest to tune the mplayer compile-time
options if you didn't already.

best regards
