Good morning. I have purchased the hd directv dvr w/tivo, and it is being installed this weekend. My question is that if I run an optical cable to my amp/receiver for the audio, is that enough to receive audio for all broadcasts? I was going to run the dvi cable from the hd box directly to my tv. Do I need to run component (BGR) cables as well. My amp has outputs for component video. So I was going to wire it this way: Dvi from HD box to TV (Samsung HLP5063) Optical from HD box to Amp/receiver (Sony strde995) Digital coax from DVD to Amp/receiver Component (BGR) from DVD to Amp/Receiver Component (BGR) from HD box to Amp/Receiver Component (BGR) from Amp/Receiver to Tv. Dvi is supposed to be the best picture quality, as optical/digital coax is supposed to be the best sound. I am confused if these connections will carry all programming (HD & SD) or if they are all necessary? Since Directv is all digital, I assume that I would not need other audio connections besides the optical. Any info would be appreciated. D.J.
