Thanks.
I toyed around with my cam on my desktop pc, and I couldn't get Firecapture to work either. It demanded a new driver, but I got the latest. Then it dawned on me, it's probably a 64-bit issue. As far as I know Firecapture is made for 32-bit. But go to 32 and be limited to 4 gigz of memory...
I got SharpCap to work, and it's just the right thing for a novice such as myself.
