Well I'm running a Gigabyte 6600 GT over DVI. If anything, the quality is too 
good! I'm driving a 50 inch RP DLP. When you blow standard def DVB widescreen 
up to that size, you do sometimes notice compression artefacts (blocking and 
ringing). I know there are some filters that should be able to reduce this. 
Also some of the channels over DVB-T have a bit too much compression. Other 
than that the picture is fantastic.

Put a HD clip on (The DivX Sharks Tale trailer is a cracker) and you'll 
fracture your jaw on the floor!
