Very interesting, sounds like a bug in the shader compiler for R6xx, but
this is not prio one on my todo list.

Yes Alex patches combined with mine seems to indeed work right.

I tried to compare the shader input and output between xvmc and vdpau
for the last couple of days now, but still haven't found all the bugs
yet, but this should just be a matter of time.

Please try the following patch with xvmc:
@@ -40,5 +40,5 @@ r600_video_create(struct pipe_screen *screen, void
- return vl_create_context(pipe, false);
+ return vl_create_context(pipe, true);
It won't work with vdpau, because it probably causes a buffer overflow
and/or crash right now.
