Hello all, I have a sony str dg820 receiver and it sounds amazing.... when it works correctly. I have it setup where my xbox 360, ps3, and uverse cable box is running to it all through hdmi and then the main hdmi output to the tv. The problem I am having is sometimes... not all the time, I have issues where the tv will flash and come back on and then the receiver displays the audio signal again. My question is.. what could be causing the audio/video dropout when I am watching movies? I am using hdmi 1.3 cables but they are cheapies from ebay. Do I need to upgrade cables or what? Thanks!
