Hmm... how can you tell them apart? Cardbus is the 32 bit backward
compatible version of 16 bit PCMCIA, correct?

BTW, to the original poster - when I think about it I'm not sure that a
P166 would have enough CPU juice to be able to keep up with live video.
With a PCI based tuner/capture card the circuitry on the card does most of
the work (writing directly to screen mem), but with a USB model the
computer CPU needs to receive and copy the data to the screen memory...

Also, a raw 320x240x25fps stream will consume about 2 megabytes per second
of bandwidth (15Mbit/sec), so the USB tuner must do some sort of
compression to be able to cram full frame video into a USB port. That's
even more CPU needed on the computer to decompress it... :)

Cheers.
