No demo to DL??? Damn them! I tried Studio7 as well as other vendors products and many weren't all that good. I'd like to try it before I throw them $100.
The problem I would get is the first piece of video captured was fine, then the second part (same tape, same capture, just a pause in the original video recording) the audio would be so choppy it was imnpossible to listen to.
I use a P4 1.5Ghz, 1Gb RAM, Firewire capture, etc. What quality settings do you typically use for capture? I haven't messed with the capture for a while, and I never got any useful help at vcdhelp.com.

edit
I just found the demo, it's 225MB, so it's snail mail a CD or long DL..
