get an easy cap usb capture device, about +-R70 on bid or buy, it works like a charm and it comes with the necessary software, even a copy of ulead video studio is included, but i do my captures with pinnacle studio 10
you can only connect a vcr to your graphics card if its got an audio video in and 90% of graphics cards dont (they only have outputs ! your best bet is an internal tv card or an external usb capture device like the easycap posted above
