I don't know what that hardware is supposed to support, but
it does look fairly broken to me.

Note that installing that could be worth a try to see if at least VDPAU
works. It is not the cause of your issues, just a potentially
But if -vo gl works with good performance it should be a good solution

So it uses XVideo. Not sure what capabilities "Video Sprite" implies

This is already really bad. It means XVideo doesn't support planar 4:2:0
Even -vo gl supports that one fine, so there no good reason for that
It can't be seen from the log, but probably the non-functional
scaling is a bug (or missing feature) of that driver, too.
(I would consider it a bug, as there's no sane reason to implement
and advertise XVideo at all if it can't even do scaling)
Note: xvinfo (a small tool to list information about the
XVideo implementation) might give some useful information, too.
