Another question:

we need video grabbers for some new productions. Any recommendations would be great. We use mostly OSX machines, G4, G5 and probably soon some of the new Intel machines. It would be good if the grabber was also usable on a Debian or some other standard Linux distribution on "standard" hardware.

the other side of the question is perhaps harder. Previously we
have played with VGA-to-Composite converters, but have never really been happy. Are there any recommendations for ways to get a composite signal from a machine easily and effectively?

Thanks in advance,
