I "roasted" a buddy of mine with some humourous home-video (VHS) at his wedding that I M.C.'d. I used something very similar to what Paul describes, a multi-media LCD projector that we borrowed from a community college. It was a very large room, probably 80x100, and
we ran on a standard pull-down projection screen about 24feet wide. At this width,pixelation was just beginning to show, but really not back behind the dance-floor where everyone was seated. You're right, sound is lousy, so we by-passed right from VCR to D.J.'s setup. It was slightly dim, but nobody had any problem at all, thought I was some kind of technical wizard. I would think that the pixels will be gone before they ever figure out how to achieve proper light levels.As I understand, LCD is light PASSED THROUGH the liquid crystal. Why don't they engineer these panels to slide into your aperature plate slot to be run by the lamps and lenses you have? Also, for any skiers or hosts of the yearly Warren Miller ski films, I see that they now have abandoned 50+ years of film and are presenting in something called "DVD Projection". Anyone see it? They still play some fairly large auditoriums, wonder how it looks?
If the evil digital does come to pass, wouldn't you rather "plug and play" with DVD discs rather than download, save, store etc, etc, etc.? Barry, bring up your projector and I'll paint my barn white (it's about 50 feet wide) and we'll try 'er out!

Depending on the quality of the lens, it could be much more than $1200.We sell a real cool Sony video projector (VPL-PX31/ZM101). It is no bigger than a slide projector (and actually smaller than some), has 2800 lumins, takes virtually any video signal with multiple inputs and with the long throw zoom lens (the ZM101 part of the model) is projectable from the booth in many if not most theatres. The sucker is bright enough that most customers comment that they don't have to turn the lights off to see the image like with other video projectors. That zoom lens is pricey though...close to $3000 as I recall Another nice feature of that projector for theatres is the ability to have the lens non-shifted. Most portable projectors have the lens permanently shifted to point up from a conference table (or down from a ceiling). I agree with Scott though...when it comes to image quality, a good quality xenon slide projector will beat just about any video image from one of these portable projectors. However, for theatre use, it make a whole lot more sense to use a DVD/video projector system in terms of control (each image will display exactly as long as it should), ease of use (no trays to update, just change the DVD on a regular basis when you change your "Movie Tunes"  DVD/Video also opens the door for moving ads instead of still slides. Getting a good video projector also allows the theatre to have another source of income by renting out the space during non-operating hours for meetings and such...just make sure your projector can handle data from a computer. Power point presentations are quite popular. Steve ------------------

Looks interesting. Like something Disney would build. Not sure how it would sound with all those beams and other things though. Onscreen advertising really is evil though. What's the point of having curtains if they're always open? It's half a notch below those dreadful television commercials most theaters force upon their customers.
