I had the same trouble running the component video of a HR10-250 among other things through a Denon AVR985. It turned out to be a thermal problem. All components were installed in a cabinet with not enough ventilation. I had the customer open up cabinet door until a get Mid Atlantic Qfan And a spare hour or two to install. Had to cut some drafting holes into the basement and a hole for fan at top of cabinet, Plug fan into switched outlet on amp and whala one quite yet cool system with no more drop out on the component video.
