Settings do help some..but any way you look at it, it's still slower than
a capture card. Parallel port cams all tax the processor a great deal
more.

Not entirely true. The White Pine 3.0 version was horribly slow with the
use of a Quickcam while the Cornell version is much faster. The same
camera, but different software utilizing the camera slowed it down.
Luckily, the 3.1.X versions seem to improve the Quickcam scenario.
