I am looking to buy one of the 36" direct view hdtv's from one of the three brands. q1. The xbr has adjustable drc and a video amplifier which the hs500 does not have. What exactly does adjustable drc do and what does the video amplifier do? q2. Do the 36" Panasonic and Toshiba direct view hdtv models from this year have adjustable drc and a video amplifier? q3. Are their any known issues with any of these models that is of great concern (horrible geometry, etc..)? q4. I noticed the Toshiba has no dvi. What is dvi? q5. Will a 480i signal from the xbox dvd fed through the component input on the tv look just as good as through a non hdtv? (wierd question, but I know cable signals can tend to look crappy on some of the hdtv sets so I was wondering if the xbox dvd will look ok) Thanks for dealing with my questions!
