Apple's DVD player is known for its lack of any deinterlacing.

It is, kinda, by XFree86 and DRI. Both their CVS repositories have the 2.2 version, just nobody has updated the Linux kernel yet. > > You've got it :-) No, there are a few things that still can be done: > > > > - get ATI to open the specs for iDCT and MC in hardware.

I'd love to get a > kernel with a r128.o that allows DMA to be used. I'm afraid you'll be disappointed. Seems it was only good for a real 'gain' as a hack on top of 4.1. Now that it's done (more :) correctly, a lot of cycles are still wasted waiting for the DMA transfer to complete.
