Yes, it works fine now with modified mplayer.

It's OK now.

The only issue I see with mplayer (apart from things not yet 
implemented) with -vo vdpau is that fullscreen doesn't respect aspect so 
stretches 4/3 or 2.38:1 content to fill my 16/9 screen.
This may be an mplayer thing - there's a post on their list where 
someone says the same, presumably using nv hardware.

usage?

Looking much better - I guess the remaining artifacts are all non float 
idct?

There has been a regression though -

  [g3dvl] remove resource_format workaround

causes quite bad artifacts on newmobcal.

There is a fullscreen issue - with 4/3 content on 16/9 screen the side 
black bars are drawn to leave 4/3 viewable, but the content is still 
stretched to 16/9 so the edges are lost.

Thanks for all this work.

Andy.
