Working OK for me now with xine and mplayer using your vlwork git, which 
I assume is the same as applying the latest patches.

Is there a way to disable mesa 2D tiling anymore? I know about the 
xorg.conf options but they don't seem to affect mesa.

I think mplayer's vdpau was written by nvidia, so maybe it assumes 
things - but then I don't know that. I do know it blindly tries to use 
yuy2 even if it's not advertised.

One thing I noticed looking at the vdpau spec on their doxygen site is 
that YUY16 isn't even listed.

When -vo gl is used mplayer will directly use 422 planar (which I assume 
is what fourcc.org calles YV16).

As for xine my current issues are the logo, mine is playing

share/xine/skins/xine-ui_logo.png with plugin gdkpixbuf

Before 422 worked properly it was distorted, now it's almost OK, but has 
a green band at the bottom. If I toggle between full screen and window a 
few times I can get it to crash - bt attached.
It works OK with xv, and actually playing a raw 422 yuy2 stream with 
xine + vdpau looks OK and won't crash toggling (it is different size 
though).


Issue 2 is that doing something that makes xine try to render over the 
video eg. skipping or changing volume results in an assert -

vl/vl_video_buffer.c:320:vl_video_buffer_sampler_view_components: 
Assertion `component < 3' failed.

bt also attached.
