I'm trying to convert some old home movies from VHS to DVD, and I would like the best video quality possible. However, I've noticed through the use of two VCR's that I cannot get an S-Video signal from the VCR to my Dazzle video capture device.

(Note: On a particular Philips DVD/VCR combo, the words "DVD Exclusive S-Video Out" were printed above the S-Video connector.)

Why doesn't S-Video work for VHS playback in these units? Any education is appreciated. Thanks!
