I purchased a set of Yamaha speakers (1 center, 4 satellite, & 1 sub woofer) and a Pioneer Elite VSX-44 receiver and I'm not sure if I have it setup correctly. When playing the radio, only the speakers plugged in to the Front R & Front L are on. I put in a Blu-Ray and got the Center speaker to work. So far the 2 I hooked up to Surround R & L are not doing anything..with the radio or Blu-Ray. I have the receiver set to Auto-Surround...I've went through the settings on the receiver and have had NO luck getting those other 2 speakers to do anything. I'm trying to find a surround sound test dvd to run to see if they are in deed working, or whether they aren't. Does anyone know a link to a free DVD for surround sound testing? Does anyone have experience with surround sound and can let me know if I've done something wrong?
