I ordered a new HDTV & upgraded to a HD DirecTV with Tivo & an upconvert DVD player. The TV has 1 HDMI input & 2 component inputs. I have all the sound running through a surroundsound system, so I don't care that the HDMI also includes sound. For pure picture quality reasons, am I better off using the HDMI for the DVD player or the DirecTV box? I'm leaning towards using the HDMI cable that came with the Tivo on the DVD player, then buying some medium-priced component cables to use with the Tivo. Thanks!
