Thank you, Luigi! Excellent advice. I started looking into it,
and discovered that 7.5 fps uncompressed, will fully utilize a USB.
Fine, so the good solutions use compression to get 30 fps but that
is still at the cost of fully utilizing the USB. Despite the fact that
it works, I am lead to believe that it is NOT an ideal application
for USB. Lots of things will be using that USB before I throw away
my new camera.
I will be looking into other possibilities on Monday.
Thanks again,
Tom
P.S. The 'Geneva' solution from Conexant (ex Rockwell) looks interesting.
It comes with a digital camera while retaining the ability to
accept composite video. Kind of like having your cake and eating
it too! No integrated tuner, but that is why God invented old VCRs.
