I'm not really expecting that. With XVideo, as I understand it, the cpu
has to do the decoding. XVideo just scales and puts the image in a video
overlay. But still, this appears to be more efficient than what the
GL-based methods do. And that surprises me... Maybe in GL the cpu has to
push data to the video memory, where XVideo pulls it from cpu memory
with DMA? I have no idea, I'm just guessing... there must be some

It doesn't tell me that it does, and I've never seen any indication of
it, so this is indeed as I expected.
