Greetings!
Thanks all who have contributed positively to this very informative thread! I have read the entire 45 pages of posts, and at times, my CPU was in danger of crashing

I have purchased a Samsung HL-S6187W 61" DLP, a Toshiba HD XA2 HD DVD player and a Denon AVR 3806.
My main goal is to get the best possible picure, and to take advantage of the advanced audio codecs available with HD DVD.
I will be having a ISF calibrator coming over to work his magic, so the TV will be calibrated to each input source (HD DVD, Dish Network HD DVR 611, cable) which will preclude me from hooking up each source to the Denon 3806 and the to the Samsung via single HDMI interface.
Being a big fan of as direct a signal path as possible, this vexes me a bit, but the trade off in picture quality obtained by the TV calibrated to each input source should outweigh the benefit of singal HDMI connection.
From my understanding, I have two options for hooking up the Toshiba XA2 to the Denon 3806:
1) Use the 8 channel analog outs of the XA2 to the Denon 3806
or
2) Find a high quality HDMI switch/spiltter
The problem with #1, I am not sure the 3806 will do advanced digital signal processing via the 8 channel analogs. After two conversations with Denon tech, I have two differnt answers. One said yes, DSP is available, and second says no, signal will just be pass through. Maybe I should call one more time and see who breaks the tie

Seriously, I want to use the DSP funstions of the 3806 AVR, not the ones built into the XA2, as I belive the Denon's to be far more flexible, if not superior. I am leaning towards believing that the 3806 DOES NOT process analog 8 in. That seems to be a function of the THX certified (part of that certification requirement) Denon models 4806 and 5805, hence the severe increase in cost for those two units.
The problem with option 2 is finding a high quality switch. I have done zero research for them. Price really is not an object, as I will pay a premium to assure best signal. Nothing fancy, just a simple switch. I have two HDMI ins on the Denon and two on the Samsung, so think that two 1x2 switches (one for the Toshiba HD DVD) and one for the Dish Network 611 would do for now. However, sould I aquire more HDMI sources..........
I have not yet hooked all this stuff up, as I am at the tail end of a remodel that will house my new home theater. Not a dedicated room, just a living room. All this equipment is still in the boxes, just waiting for the day...
I was hoping someone here might have some advise or experience with my proposed setup, as well as where to start looking if the switch seems to be the answer.
Thanks in advance for your time and trouble...
Best,
