Don't worry, with emails I always interpret thing in a flame-preventing
way. Or at least try to :-)

Didn't read, but not necessary, since I found the problem.
What causes this massive slowdown is using textures with border pixels.
Don't know why, probably ATI doesn't support them properly?
I guess I'l change it then for the bicubic thing, despite the possible
quality loss.
I won't change it for the 3D lookup though, so unless someone can tell
me a workaround or ATI fixes this, yuv=6 won't be useable for ATI users

Yes, I tried it, but it does not support ARB_fragment_program, only GLSL
and the DirectX stuff...
And it wouldn't have helped with this problem anyway.
