I have a Pioneer VSX-815 7.1 receiver hooked up via optical to my PS3 and I stream movies from my PC to my PS3 via PS3 media server. Now, whenever I play a movie on occasion during a loud scene in a movie the receiver will shut itself off and briefly display "OVRLOAD" meaning it was somehow overloaded? Now, the obvious answer is I have a short somewhere in my cables, but I double checked them recently. I suppose I could always go back and reseat all the cables to the back of the receiver. The other answer is I am simply overloading the receiver and it doesn't have enough power to produce the sound to all 7 speakers? This is after all a $250 receiver I bought 3 years ago. Let me know what you think!
