I have been lurking a while and have a friend who is not buying an HDTV because of the movie channels threatening to encrypt movies. I don't think that he's against the encryption, but it had something to do with the output of set top boxes and inputs on HDTVs, and not being able to see them at full quality. It sounded like he was saying that the current HDTVs don't have an input capable of the full HDTV bandwidth. Composite vs. Component or something like that. Can someone break down the digital in/outputs of HDTVs/settop boxes/DVHS and their picture qualities? Does anyone get the jist of his argument and is it a valid point? I also saw that Mitsu's HDTVs are "upgradable", but most other manufacturers aren't. What is this really referring to? People are obviously buying TVs, so are you taking a risk by doing so now?
