tweeterguy has it right. There are masses of different TV models and the only way they can come close to working the same way is to limit them to use as monitors.
You want to use all the inputs of a TV? Then plug in the TV, plug the inputs into the TV, and don't think about all those A/V receiver and surround thingies. They're just too complicated.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
