OT: VHS to DVD.

I have been trying to transfer VHS tapes to my computer using a HDE 3 RCA to USB Audio/Video A/V Camcorder Adapter Cable for TV/Mac/PC. I have Windows Live Movie Maker. The computer does not recognize the VCR.  I have tried plugging the cable into the USB ports on the front as well as the back of the computer. I have a ZT Desktop PC with Windows 7. Any suggestions?
