HTPC problem with Denon AVR-3311CI

I recently replaced a Pioneer Elite VSX-33 with a Denon AVR-3311CI. Since upgrading, I have had trouble getting my HTPC to work consistently. I use HDMI 1.4 cables. (Not sure about the HDMI to DVI cable.)


Here are the problems I am having:

• When I switch inputs, my computer doesn't recognize the HDMI audio out when returned to the HTPC input unless the cable is unplugged, then plugged back in.
• Often times when I load a Blu Ray in PowerDVD 12 (latest patch), the projection screen flashes pink. This happens at random more often than not.
• I can't output to two monitors at once despite having two HDMI outs. I could on the Pioneer. Perhaps not a feature implemented?

My signal chain for the HTPC:

HTPC (AMD Radeon HD 6670) --> Denon AVR-3311CI --> Digital Projection SX+ (Via HDMI to DVI cable. The projector will be replaced in a few weeks.)
