Need advice on Home Theater Set-up

I don't know that there is a best way. A lot depends on your preferences. These are mine. For video, if the HD box has HDMI or DVI, I would connect that output directly to the corresponding tv input (If HD box has DVI input, use DVI-HDMI cable). I would connect DVD by component cables. For audio,I would then connect analog cables (not necessary if HD box has HDMI output) from HD box and DVD player to tv. Next, I would connect digital out cables from HD box and DVD player to digital inputs on receiver. This configuration allows you to watch sources without turning on the receiver, if you prefer. This suggestion assumes certain facts about the connective capabilty of the equipment. I have no direct experience with the tv, HD box and receiver you list.
