New here, just got myself a Denon AVR 791 and have been having issues with it. My current setup is using the 791 with 5.1, using HDMI and optical audio out with my motorola comcast box, HDMI and digital coaxial out with my LG Blu-ray player, and HDMI for our LG 42 TV. The 791 has been unable to retain picture and sound without constant cutting out adjusting. This happens when I watch anything on the DVR (it will start adjusting picture and sound for no reason), and tonight we watched a blu-ray for the first time and it did the exact same thing.
You can see the indicators on the display go in and out, watching the HDMI indicator go, and various others as well. It will not keep the video or audio displayed for any amount of time. I finally had to stop, and run the HDMI direct to the TV instead of through the receiver. Same solution for the TV. I've not run across any info for a fix. Has anyone else had this issue? It seems to be related to the ability of the receiver to detect/hold a signal via HDMI, as though it cannot accurately autodetect the signal like it should. Any help would be appreciated, as I'm really unhappy with the capabilities of the video at this point.
P.S. I can't get my menu to show up on screen. Everything is run via HDMI video wise. Any help on both these matters greatly appreciated!
