I am thinking of getting a Sony VW10HT projector, but since I have never had one, or even seen one, I was hoping someone can answer a few questions that I have. Can I easily hook this up to my DVD player using "Component Video Cables"? Do I need to "Calibrate" the projector to display proper colors/contrast/black level? How long does a projector last? My family intends to use this projector at LEAST 6 hours A DAY. How long will the bulb last if used that much? I read somewhere that each bulb costs $500 dollars each...Is that true? Can anyone tell me anything else interesting about projectors? I'm *REALLY* considering getting one.
