OK, just blew the dust off my old PC and removed the card that I put in specifically for this purpose.
It is WinTV as I thought. Software is by Hauppauge. see here
Hauppague.co.uk
As with all things it has moved on since I first looked and you can get USB versions now as well. I suggest having a 'mooch' around the internet or PC World then buying it online if you are not in a hurry like I was. There will be several types, manufacturers etc, its down to how you want to do it really.
I will say that quality is not going to be as good as from a dvd especially when the tape has been used a lot but when you need to copy a one and only then I just put up with it. I guess there is software that will 'spruce it up a bit' once it is in digital format but I have not felt the need to seek it out.
Good luck with your project let us know how you get on.
Now do I put the card back in the old PC or in the new one
