I have Cablevision service in New Jersey, a Scientific Atlanta 4200 HD box, a Denon AVR-4306 receiver and a Mitsubishi HC5000 projector. I have DVI out of SciAtl box to HDMI into the 4306, then HDMI from 4306 to HDMI into the projector. This worked great for the first 5 weeks of the setup!!! Then, a couple of nights ago, I got a flashing DVI/HDMI Copy Protection message (audio was still working). Called Cablevision - many customers reported issue - they must have flashed software to boxes. Workaround is to use component since "that is what Cablevision supports" - pretty bogus response and company position! Picture quality has not suffered, but I do notice some pixellation watching sports via component. With DVI/HDMI there was none and I suspect it was because there was no compression/decompression going on. Is anybody able to figure out a solution? Seems like going component after DVI/HDMI was working well is a step backward.
