Well, I have a little different "spin" on the situation. I think that all the HDMI inputs need to go to the HDTV first, not the HT receiver. Why? The easiest place to fix/ compensate/ adjust the lip sync/ video delay problems that we are starting to see with HDTVs is in the TV itself. The HDTV "knows" how long it is going to take to upconvert or whatever, and can lock the audio to the video frame to frame. Let the TV do all of its magic and then send the audio over to the receiver through either a HDMI or optical cable. Long term, probably better to do it with a HDMI cable.
