I am unable to get a digital signal recognized from the DVD changer to my DLP when connected via HDMI - DVI cable (TV only has DVI HDCP input not HDMI). My Samsung 931 DVD player and Dish 921 HD PVR DVI outputs both work with my DLP (connected via Gefen 4 way DVI switcher). I have attemped to connect the Sony directly to the TV instead of through the switcher with no luck. I also took the Sony to Circuit City and had them hook it up using my cable to a DVI equipted TV there. It worked. Any ideas? I am going to have a Circuit City repait person out if I can't figure it out (as I assume it must be the TV). Since the TV is under a service agreement, my hope is they will either have to make it work (since the TV is documented as having HDMI compatible DVI inputs) or replace it with one that works).
