So if there's anyone out there that has any experience with Pioneer A/V Receivers? I'm having an issue with being able to get signal through my Pioneer VSX-521-K through my system. Basically, my setup runs just fine from the HTPC to the TV through HDMI just fine, but any time I attempt to put the receiver in between, all I get is an alternating blue/black screen that recycles every 2 seconds or so, with no sound as well. I know that the receiver will pass video through for some sources, as my XBox passes through the receiver to the TV just fine, I just can't figure out the HTPC at all. I'm running my HTPC with an Asus F1A75-M board that I've tried with both current and older drivers, but I can't seem to get it to work. Could this be an HDCP handshake issue, or does anyone have any experience or thoughts on how to get this fixed? I can't seem to find anything anywhere online about it.
