My Gateway DVDR plays live TV through component also. I have it hooked to the Component1 input on my RCA HDRPTV. One benefit of this, on my TV anyway, is that the picture when played through the tuner in the DVDR is visually better than when I watch through my HD STB via S-Video. However, I do have the RF cable plugged into the DVDR first and then out from the DVDR to the STB which is then in turn plugged into the TV via Component and S-Video. BTW-I watch HD channels via the STB's Component outputs plugged into the Component2 input on my RCA.....the HD channels are stunning, especially Discovery HD Theater!
