If you could get fxtv to dump YUV frames you would find it would be much more
efficient..

The BT8x8 cards can generate such frames, and mpeg encoding starts off by
generating YUV from RGB (and it is a major CPU killer - witness how much CPU
the Xv extension saves you when playing a movie - the CPU no longer has to do
YUV -> RGB)

And, uhh, no, I have no patches :)

This is good work :)
