Jason,
Thanks for the quick and helpful response, it is about what I thought. One caveat that I did not mention, was that I live (and purchased) this system in Argentina about 7 years ago. As mentioned, now I want to have the cable TV and/or streaming services from Apple TV have surround sound...
I have a Phillips 5 in 1 Home Theater system that works fine for me, it plays DVDs in surround sound. The problem is; it has no audio input so I can not get surround sound when I stream Netflix to my TV or play a BlueRay that is hooked up to my TV. So the question is, can I buy a 5 in 1 DVD...
