When watching Netflix through the PS3, I sometimes get feedback or whatever it might be called. It causes my speakers to thud and sometimes causes the receiver to completely shut off. I have the PS3 running into the receiver via HDMI. I switched to running video only through HDMI to TV and Optical audio to receiver. Had same problem. Receiver is Onkyo TX-SR705 and handles pretty much all forms of Dolby Digital. This only happens when streaming certain Netflix files. Some of these files have an audio option that allows me to switch from DDP5.1 to Stereo. When I switch, they play fine. Pretty lost on this one. Any assistance would be greatly appreciated.
