Here's a tough one. My rig has the Sony DVD player and Black box to control what you viewing.... DVD, Sat, roof antenna. Over the week end we tried to watch Sat on the front and play a DVD (for the grandkids) on the rear TV. We had surround sound everywere coming from the DVD and sound coming out of the front TV from the Sat. I investigated some and couldn't find a place to turn off the surrond sound thinking we then would have sound coming from each TV that could be managed by the remotes. Any suggestions?
