Ok... I have read a lot of stuff and though I am still feeling a bit overwhelmed, I think I have my concern boiled down to a simple question.
Here's my situation - Mitsu WD62628 1080p (wobulated) 62" DLP, and I'm putting in a new game room/media room.
I only have one 1080 HDMI input on the TV (the other is maxed at 720p as a computer input... what a beating). Both are pre-HDMI 1.3.
So.... if I get the 605 and run my DISH HD DVR and a PS/3 both through the 605 HDMI ports and then to the TV via HDMI, will I suffer any downconversion?
Meaning will I get 1080i from the DVR, 1080p from Blu-Ray discs via PS3, and 480p via regular DVD via PS3?
If so, then I'm IN and I will just avoid the component inputs for anything other than my old PS2 (Guitar Hero

) and any other non-HD sources since the max output via component it sounds like is 720p.
Does this make sense? I would very much like to get this rcvr and not pay double for the 805 (I think that's the next model up) if possible. I want to spend that $ on some nice speakers.
I'm hoping my assumptions above are right and I can confidently buy this receiver and be ecstatic about it.
With but a simple answer from one of you fine folks, I'll be SET and completely stoked.
Thanks in advance!!!!!
