I believe the Dazzle 80 was using the VFW protocols. Laptop not available for definitive answer right now.
I've learned much with the Canopus box, mainly to use the "type 2 DV-avi" file format for capture. Much more compatible with other programs. Vdub has no problems seeing/reading/editing the captured files of massive size (12gigs!) I use Scenalyzer Live for DV capture, well worth the low registration fee.
If you haven't been to
DVDrhelp, try it! Especially the "tools" section. Another good site for info is
Afterdawn.
