Actually my opinion about XvMC is that you don't want to use that on
1080i HDTV signal. This is because XvMC doesn't support deinterlacing
and you want deinterlaced signal, or you have combing in your picture.
I've tested this with Euro1080, Nvidia XvMC, DVI-out and Sony projector
on progressive frame format. Maybe Sony's deinterlacer could improve the
picture but due Nvidia driver timing problem I cannot confirm this.

This because XvMC 'captures' MPEG data before it can be deinterlaced
by host CPU. And I am not aware of HW/GPU deinterlacers other than
Nvidia 6600/6800 with purevideo, but purevideo support is Windows only
AFAIK.

Best regards, Jori
