I too have the same problem having done several uninstalls/installs. if I go to convert a VHS, during the recording process, I have no video. But if i record and play back, the
video is there. and I can take that video and edit it or work with it in any way i choose. So the video is being recorded. My drivers are right. I have another machine right next to
the filing machine and it run Vhs to dvd just fine. I think its a Windows problem ( My system is windows 10 x64 pro)
Hope this helps
