I just started casually reading up on all the blu ray/hd-dvd stuff and wanted to know IF I ever did decided to upgrade(doubtful at this time because I'm very happy w/ my set up and really see no need to upgrade again) other than a new player, blu ray or hd what else might I have to upgrade? I have a denon 3802 receiver and a mitsubishi 46802 hd ready widescreen tv. Would I have to upgrade to newer receivers/tvs because neither has this HDMI output I'm reading about? Exactly what is that output for audio? video? or both? and could I still get the most out of a new dvd player if it was hooked up using components? Like I said just reading up for now but if I had to buy all new equipment just to get this upgrade then forget it. This whole mess w/ dual formats just seems annoying and unnecessary right now. There's nothing wrong w/ dvd and this looks like the companies just trying to squeeze more money out of everyone to me. But it's still best to be prepared just in case the day ever comes where one of these formats replaces dvd all together just like how dvd replaced laser disc.
