I just recently purchased a Panasonic TH-50PX75U Plasma and the Panasonic SC-PT650 Home Theater System. I didn’t want to pay for the installation so we did it on our own. The only problem e have encountered is we can not get the surround sound to work when just watching cable or playing video games. It only works when using the DVD player. Is there a way to make it work?
Will these answeres provide surround sound when using Nintendo Wii?
