I have a VCR with a tape of something i want to transfer onto my computer. I also have a usb-av connector, the USB goes into the computer and the av is in my digital out of my vcr. So I hook all this up and I go into windows movie maker and click capture, but only sound comes through. Everything seems hooked up right, and I don't know how to get this to work. It works when i go tv to computer but the screen on the capture is so small so i used my vcr. Any help or tips would be appreciated.
