How to shoot a Video projector in daylight? at DVinfo.net

I have to shoot some video in a classroom in DV. A teacher is going to stand in front of an interactive whiteboard, which is basically a video projector shining onto a white board and in normal daylight

Any tips on how best to approach this with the V1?

TIA

a nice trick would be to put a polarizer in the projector and another (90 deg angle) on the camera, so the projector is dimmed.
you could even add a light with another polarizer (same as camera).

I'd rather not have to buy filters as I'm not being payed much as it's for a school. It's more what shutter speed would get rid of flicker if the projector was running at 60hz or 75hz?
