I am having a really strange problem with my VSX-01TXH. I have a PS3, Xbox 360, and a Comcast HD box all hooked up to the VSX-01TXH using HDMI cables. When I am watching Comcast, I get video dropouts that last about 2 seconds about twice an hour. I have played the 360 and the PS3 for hours on end and never had a single dropout. If I hook the Comcast box directly to the back of my TV using the same HDMI cable, I have absolutely zero dropouts. Does anyone have any idea what could be causing this issue?
