I have an older stand-alone DVD player which I want to give to my daughter, who only has a laptop (no TV). I bought connectors where the White/Red/Yellow (audio/audio/video) DVD player outputs resolve in a USB. It fits fine in my laptop, but the OS (Win 7 64 Pro) won't recognize it. I tried "Discover Devices," but still it couldn't find it. Any ideas what to do next?
