I looked around, but can't really find any solid answers. Basically, I have 3 TV's in my house. Two of them have HD boxes from Comcast. My TV upstairs is just plugged into the the wall. I used to get the channels I wanted (A&E, FSN Detroit, ESPN, stuff like that). Once the switch over happened, all I get is crap (mostly local, best I can get is TBS). Is there anything I can buy over the counter to get more channels, or do I have to pay the extra $10 a month from Comcast? The TV is a newer Vizio (about 1 1/2 years old). Thanks for any help.
