HTPC and Denon Receiver

[Rokspidr]

I have a custom built HTPC (specs to follow) that is connected to a Denon 2808 AVR via HDMI cable. The Denon is contected to my HDTV via a hdmi cable. I continue to have problems running blu ray video from HTPC to Denon to TV. System will play bluray to my HDCP compliant monitor via DVI with as long as Denon is not connected. Connect HDMI from HTPC to PS3 and plays video just fine. Cyberlink BD advisor says not connected to HDCP compilant source. This is incorrect. Any help in this area would be greatly appreciated. I have been combating this problem for months and have spent a lot of $ on trying to fix problem.
HTPC Components:

ASUS P5B Deluxe
Intel Core 2 Duo 6600
2GB Ram
Lite-On Blu Ray Drive
Raid 5 WD Caviar HD
Nvidia 8600 GTS (HDMI out and DVI Out)
ASUS HDAV 1.3 Audio Card (new in market)

I've heard that the xx08 Denon line is finicky with HDCP & PCs, though I don't have any direct experience with it. There may be a firmware update that'll help though. I'd suggest contacting Denon directly and asking about this and they may be able to help.
