Forgive me for making a whole thread to get some clarification for myself. I've seen references to QAM channels in a couple threads and I think I have a limited handle on that, but I have another question that will no doubt show my ignorance. I'm wanting to upgrade to either Tivo HD or the S3 box. However, I'm just using my regular coaxial cable connection to get my cable service from TW. My question is, will I have program information on Tivo for my over the air HD channels? If not, what do I need to do in order to have HD channels show up in the program guide? I know that it's not absolutely necessary to have the program information, I've just gotten used to the convenience and don't wish to part with it if I don't have to. Thanks!
