Yes. Plug one of these into the SCART out socket on the back of your VCR . . .
Get a composite video lead (as in the pic below) and plug one end into the correct socket on your WinTV card.
Plug the other end into the yellow socket on the SCART adapter you'll have plugged in the back of your VCR.
Then get a stereo jack to phono lead like this one . . .
I'm fairly sure you'll already know by this point, exactly where to plug the red and black phono plugs
from this type of cable, and which socket on your PC's sound card the stereo jack needs to go into.
After all that, you'll then need to make sure "Line In" is active on the Windows sound mixer . . .
Right, that's all the hardware done and dusted. Now go and get some videocapturing software. VirtualDub is
a particularly good, full featured package for that purpose, available at a 100% unbeatable price . . . It's free!
It captures video in uncompressed AVI format, so you'll need to ensure you've got a generous amount of
spare capacity on your HDD. You'll also want to get a program that'll encode your AVI's into smaller files,
such as AVI2MPEG, RealProducer, Windows Media Encoder or any other suitable program.
Now though, it's gone 04:20, and I need to get some kip! Assuming at least one other person round here
has used VirtualDub, I'll leave up to others to guide you through how to capture your AV content with it.
