Well... changed input device to a Dazzle (100?) and got video through VLC
Capture Device and Convert.  Came out as Black and White signal.  Starting
to read the VLC manual / help.

Using RCA inputs for video, Left and right audio (Dazzle's inputs).  Have
access to another usb/coax dongle....will be testing that tomorrow.

Any thoughts/recommendations?

Joe
