My experience with video projectors is that they are capable of changing formats and video sources - e.g. 4:3 to 16:9 / RGB to SVHS - BUT, you need to display a menu on screen to select the option. If you are running a mixed program, this isn't exactly a polished presentation for theatrical purposes. It may be acceptable for a presentation at a business meeting, but it is comparable to running an SMPTE 35PA loop for the audience before each subject in the program.
Secondly, projection is projection, whether on video or film. If you set up for 4:3, 16:9 will be letter boxed. True, you could zoom out to fill the screen top to bottom, but then you also have to open your side-movable masking.
Also, operating the zoom requires a focus readjustment in my experience.
Maybe I'm spoiled, but 35mm film is treated as a permanent installation that is professional because these projection adjustments are pre-set. Video has the air of an amateur in a home theatre, where even a simple aspect ratio change is done on the fly.
Hitting the screen correctly from the first frame just doesn't seem possible with the reliance on zoom instead of fixed focal length lenses, when aspect ratio changes are required.
I will add that I have projected video with the occasional 16mm thrown in to the programming. Original, independently produced 16mm is very refreshing to my eye, compared to video. The virtues of film prints without the mass production techniques requiring internegs that are the norm with the typical major studio offerings are plain to see. Video is cheaper and more convenient, but in my experience, it has yet to demonstrate that it can match or surpass film when projected, if the goal is the highest possible image quality.
