I've got a Barco Graphics 808, and I'm trying to get it working with my cable company's HD cable box. I've got an Audio Authority 9A65 transcoder to get from the component output on the cable box, to the RGBHV input on the Barco. All non-HD channels work perfectly fine. My progressive scan DVD player works fine too. I'm not getting any results for the HD channels. Well, the Barco tries to adjust to the signal, but I get a very distorted screen for a second or two, and then the Barco tell me "no signal". The best way I can describe it is like when you try to view a premium channel when you're not a subscriber - sort of like it's scrambled. When I switch to the HD channels, the transcoder tells me that the signal is 1080i. Does the Barco Graphics 808 work for HD? Or does it look like the cable company doesn't have the HD channels turned on or unscrambled?
