G400+(insert video capture card here)

[Newbie]

Hi, I was wondering if any G400+WinTV owners out there would mind rating their Hauppauge cards as to their TV picture quality and video capture abilities. Do the WinTV cards use the same type of hardware codec the Marvel/RR-Gs use? What formats and resolutions does it capture in?

Can anyone suggest any better video capture/TV tuner cards to pair up with a G400 other than RR-G or Hauppauge WinTV?
Thanks.
