What's a decent Analog to Digital converter for my LCD TV?

Okay, I have an LCD tv, and a cable box for my signal, but how come I have to pay extra for HD programming? If the US just went through this huge "switchover to digital" issue, isn't the broadcast now already digital? And if it is, what resolution is it broadcast in? Do I have to buy an external converter to get an HD signal for my hdtv?

Answers to your specific questions:
1. Why do you pay extra for the HD channels on your cable? It's simply free enterprise. The cable company owns facilities, and provides services to customers on those facilities. They charge fees for the services, and fees vary according to the service provided. HD channels take up more bandwidth on the cable than standard-def (SD) digital channels, so they feel justified in getting a bigger return from them.

2. After the U.S. digital cutover in June, aren't the broadcasts now all digital? Yes, but the June cutover had nothing to do with what you get on your cable. That only affected over-the-air (OTA) transmissions. Besides, your issue really has nothing to do with analog signals. You have a cable receiver (digital set-top box, or STB), so the channels you are receiving are at least SD digital.

3. Digital television (DTV) broadcasts are in what resolution? They can be 480i for SD, 480p for "enhanced definition" DTV, and either 720p or 1080i for HD. NBC and CBS prime time network programs are in 1080i. Fox, ABC, and ESPN use 720p.

4. Do you need an external converter to get HD channels? No. On cable, all you need to do is subscribe to their HD channel package. Your STB doesn't care whether its input is SD or HD. Same for satellite. For OTA, you need nothing extra at all, assuming you have a very good antenna and are in an area with good DTV reception.
