YIKES !
What on earth (or what out there ...) is
AC3?
Something different (or in addition) I'll need to the system I was about to order?
I just was hoping to get some
PBS stations .. some news ... maybe communicate with some extra-terrestrials ... but not a whole bunch else.
Obviously, I'm new to this stuff.
PS: One of you that posted is from Maine? My wife and I went to Acadia a couple of years ago ... aw man, ... one of Earth's truly heavenly places !
... and the blueberries everywhere! Incredible!
