I am an old Audio hi fi buff but completely new to Home theatre. I finally got rid of my old refrigerator size rear projection tv and bought a 70" sharp LCD/LED and Onkyo reciever. When I watch movies the jacket always tells how the sound track is encoded and I set my reciever to the appropriate decoder,
However, I mostly just watch HDTV on u-verse. I don't find any information on the channel guide of any type of sound encodeing for TV shows or movies. Should I assume they are all just stereo? And if so is there a prefered setting to give a surround sound effect?
