I also have this problem, using the onboard GF4 MX video of a Shuttle
SN41G2. Adjusting the gamma (to 1.45) in XF86Config and playing with the
inputs on my PVR-250 hacks around the issue a little, but not enough. As
a result, recorded video is significantly lower viewing quality than
off-air.

Anyone who knows lots about signals on cables, DACs, those sorts of
things want to comment on what causes this? (Even though it's a little
OT, since if there are generic steps to take it might be useful to many
users.)
