I'm trying to switch all my HDMI sources with my new Pioneer VSX-23 rcvr. All works well except my Comcast DCT6412/2005 DVR, where I get a combination of no video (blue screen), wildly flickering video and a partially obscured error message saying I should use component instead. Video from the DVR's DVI port directly to the proj works great using the same cable (actually I've tried several DVI-to-HDMI cables with similar results).
I've searched around here a bit and it seems like this is most likely a Motorola/Comcast issue where the DVR firmware doesn't like to see any additional devices in the HDMI chain. Most of my searching led to results from 2007 or earlier though, and I'm hoping that a fix may have been implemented in the mean time? If there's an easy answer, I'd sure love to hear about it...my searches didn't turn anything up unfortunately.
BTW, I'm waiting to hear from Comcast but past experience makes me feel like the answer won't be coming from them. I'd appreciate any info you guys could provide!
