I'm a bit late to the party, but I just got an HDTV. The TV is in our living room which is also home to our DVR receiver. I'm not exactly sure the specific model for the receiver, but we just got DirecTV back 3 months ago so I'm sure it's whatever the current non-HD receiver is. We hooked it up with the RCA cables and the picture looks pretty meh. My mother doesn't want to pay the extra cost to get an HD receiver so I'm trying to maximize what I can with what I have. I hooked my Xbox360 up to it via component and it looks fantastic. Can the non-HD DVR support that? What about S-Video? For a hail mary what about HDMI? What is the max resolution this can output? 480P? Thanks for any help.
