Hi!

First thing: A great idea!

I have connected my VDR box to my TV via a DVI-to-HDMI cable, set the
resolution to 1920x1080 and let the graphics card do the upscaling
instead of the TV, because the quality looks IMHO better this way. But
here still the same problem is present, the refresh rate of the graphics
card is not bound to the field rate of the incoming TV signal, so I can
either disable sync-to-vblank and have tearing artefacts or enable it
and have an unsteady framerate.

I wonder if your patch could be applied to a DVI/HDMI connection, too?
Its a Radeon X850 currently with xf86-video-ati 6.6.3 and xorg-server 1.4.

Ciao

Martin
