Hmm, that's hard to answer. It'll be better than VHS. Potentially with
a fast capture machine (a good analog input and a fast machine) you
could capture at 30 frames / sec - but then, powerpoint slides hardly
need to capture at that rate !

Right, well a DVD recorder would record NTSC or PAL resolution, so
think 720x576 or 720x480-ish. Then again, most projectors will work
happily with that cause they're often used to project DVD source
content ;-)
This sort of card also captures at those resolutions :

Something like the "Canopus TwinPact 100 Scan Converter" would appear
to match your requirements using the remote control (scroll or seach
for that text in the above page), though I've never used one.
Cheers - Neil
