Hi, i have been looking through the forums and seeing words like HT,DTV and such used and have been wondering what those stands for. I just got a new 48" JVC Widescreen HDTV and have a few questions. 1. It has a VGA input on the back. I am wondering what that is for. I will be getting satilite soon and i don't wanna use RF cables. Are the VGA outputs on satilite recievers? I am not going to have enough money to get a HDTV reciever yet so i am hoping the satilite recievings have that VGA out and not the HDTV recievers. 2. I got the TV at Good Guys so i have 30 days to take it back if i don't like it. I got it for $1799 so i was wondering if there is any other TVs for that price that would be better. 3. I have a DVD player but it doesn't have PS output but it does have component output. How much of a quality difference is it? 4. Where can i get tests to tweak my tv or whatever? Thankz, sorry if this might not be the right forum.
