All I'm going to be using the TV for is video games and DVDs. So my question is, if I get and HDTV set, will I need to get an HDTV tuner as well in order to get the best picture quality on my games and movies? And my other question is, would it even be worth it? In terms of an HDTV set I'm looking at the Sony KV-32HS510. And in terms of a non-HDTV set I was thinking of either the Sony Wega KV36FS320 or the Sony Wega KV-36FS120 36. I'm pretty new to this guys, this will be my first new TV in a long time so all help would be greatly appreciated.
