My Card (Radeon 8500 AiW DV) works in xorg7 out-of-the-box with tv-in.
but the tv-in picture isn't very well. there are stripes in the pic. and it's rustle.
settings are pal-tuner and europe-west (for german)
it seems that AiW Tv only works with video overlay?! could that be a reason for a bad pic.?
here one screenshot
hope someone have one idea to get a clean tv-in pic.
