Question: Now will the TV's with a digital comb filter built in still need a converter box or is that something different?
Totally different thing.
I made the choice about the car I drive. I didn't make the choice about whether television was going to continue to be free or not, the money grubbing pricks in gov't did. Vote the SOB's out, every one of them.
You also made a choice on what tv you buy, and aparently, you suck at buying tv's. Anyone with a 1/2 a brain knew this was coming for years. And if you still have a dino tv, time to upgrade, they are cheap.
