Thanks for the help!

(a) Yes
(b) Cable
(c) Yes, 2
(d) commercially made cables, I hope they're properly crimped
(e) PCI, no brand chinese junk, Philips chip

I plugged the cable into a TV, and the picture looks fine on all 
channels. So I think the noise is being added by the computer.

Regards,

John
