My 770ED certainly can't. The best I can get (by preallocating disk
space and enabling DMA) at 30fps with only the occasional dropped frame
is 240x180. That's in 16-bit RGB mode and 16-bit stereo, 32KHz.

The resolution is fine for my purposes, but it's still unusable.

There's some periodic video glitch on the video input that gets
captured. I tried installing a newer video capture driver, but
then the supplied Asymmetrix Digital Video Capture software wouldn't
start!

A new Video Features driver appeared on the IBM web site a couple of
weeks ago but I haven't tried it yet. Maybe it'll do somethng?

The fact that they are still fixing bugs for a product that they don't
even sell anymore (that I bought) is somewhat annoying.
