Me too, I've grabbed the output of xvinfo and it seems normal, so I
suspect after I've next restarted there won't be any difference - AFAIK,
xvinfo only reports the card's capabilities, not its current state.

I don't think it's the size of the movie that matters, because the
driver only ever sees a few frames at a time regardless of the movie
size (I've repeatedly played a 13GB digital TV stream without

Interestingly enough, after perusing the output of xvinfo it lists
alternate ports - the "NV17 Video Overlay" which I normally use is port
177 and this is the one that no longer works, but my secondary monitor
plays video with the "NV17 Video Texture".  My primary display also
supports this 'video texture' as port 178 and if I run mplayer like

  mplayer -vo xv:port=178 ...

Then I get video output!  Presumably it's not quite as accelerated, but
it's a *lot* faster than the -vo gl variants.  Looks like this'll be a
viable workaround until the problem is fixed.
