I know that one way to get HDTV is with a HDTV antenna. But, can you get HD quality video through Digital Cable with a HDTV, or do you HAVE to go with the antenna for now? Also, which do you guys feel is better: A straight-up HDTV set, or an HDTV-Ready set, so you can get the HDTV decoder thingy seperate? Thanks! EDIT: Also... does Satellite TV broadcast HDTV?
