With regard to the OP's request :

"They might be using Mac, Windows, or Linux ..." <snip />

"I want to record exactly what is projected onto the big screen,
whether it is a PowerPoint presentation, or a demonstration in another
software. "

"I can't put something on the computers as I don't have access to
them, and each is a different system."

The practical reason why I didn't suggest Producer is because it's
inappropriate for this use. Apart from anything else, he doesn't want
to install software on the target computers (constraint 1), nor could
he (constraint 2) if it was a Mac or Linux box, or (constraint 3) he
didn't have access to install software on them beforehand, as stated.

And finally, Producer really only addresses powerpoint, AFAIK it
doesn't do the screen capture profiles a-la windows media encoder. So
you couldn't capture the output of "another software" (constraint 4)

Hope that clarifies the suggestions so far.

Cheers - Neil
