I am still on the low side of the learning curve regarding home theater. I have learned from this message board to buy Axiom speakers and the Yamaha RX-V1400 receiver and I am enjoying them immensely with my front screen projector, Denon DVD player with farouja processing, and Comcast HDTV. The hardware seems pretty straightforward.

My confusion concerns selecting the proper sound processing mode in my Yamaha Receiver. What is my best strategy to hear the best sound possible for 5.1 HDTV, DVDs and audio CDs? Should I use THX, Dolby Surround, Dolby EX (whatever that is) or Dolby Pro Logic II and IIx? I can go 7.1 but I have not yet set up rear speakers. I'd hate not to be taking full advantage of my audio system so any help or referral to a good article would be appreciated.
