Getting Digital channels?
First off, I have a 40" Samsung LCD HDTV (LN-S4051D to be exact) and for the life of my cannot figure out why I can't get digital channels when other people in my fraternity house can. I was under the impression that since I have the built-in tuner, I would get these channels like the other two guys and our main TV. The other channels I'm talking about are listed as 80.1, .2, .3, and other decimal point numbers.
I've done the auto channel search and it won't pick them up. Do I need a box from Comcast to get these or something?
