I just got a Yamaha RX-V3800 AV reciever and it has HDMI switching. I have a Nakamichi vu50p plasma (1080i capable) and 722. I hooked everything up via HDMI and then have HDMI cable going to the TV. TV only has DVI so I am using a DVI to HDMI converter. It detects a signal, but it is black. I try to go into the GUI for the reciever which is a much lower resolution and it detects (black screen) then about 2 seconds later is redetects. It does this over and over until I exit out of the GUI then it goes back to the higher resolution (black screen) and stays. I can get video through component (only by hooking up the component cables between the reciever and the 722 in addition to running them to the TV.) Anyone have any suggestions. I didnt try a dvd player yet, but if the GUI will not come up, there is something going on.
