Tough, it's probably cable too but the problem is that I love football and I must watch football on cable but I will still stick to cable internet since I can't live without it plus I have over 200 TV shows on DVD and DVD movies, why need cable if all the shows I want is on DVD?
Use DTV and rabbit ear antenna to get those in HD over the air on older TV. That what I am doing right now. It works nicely. If you have antenna on your house, use that to get more coverage on digital HD channels than old fashion channels.
I do have extra DTV converter at my home. I need to get rid of it because I have surplus of it. Bought two at Best buy when needed only one.
