Comment # 3 on bug 73191 from Rachel Greenham

I'm away from the computer so I'll try more tests later, specifically:

1: Test again with latest master, on the offchance it got inadvertently fixed
there by other work since I reported it.

2: Test with XBMC running standalone, instead of in the Unity (ie: with
composite) desktop. XBMC devs advise that while composite being enabled makes
it suboptimal, it shouldn't break it like this, and indeed as reported on
earlier versions it didn't. (xmir definitely isn't enabled btw; that utterly
fails to work for me, won't even start.)

In the meantime just noting: Contrary to the previous commenter it *worked* for
me on mesa 10.0 and 10.0.1 and only failed from the specified commit onwards

Also to reiterate, the player I'm using is xbmc from the fernetmenta branch,
which is where, I understand, the vdpau/radeon work is going on at the moment.
I was having issues enabling vdpau in vlc, but I'd given up on that some time
earlier and was my impression it was an unrelated issue, but I can look at that
again. If you have a preferred vdpau player for testing issues like this let me
know. :-)

I could upload some example media showing the problem but as noted already, it
affects *all* h.264 playback for me (live tv, handbraked ie: x264, raw-bluray),
so I reckoned uploading a sample was redundant. :-)
