Problems with Video Capture Cards

On my older XPS 15 7590, I have been successfully capturing VHS tapes, converting to digit, using the Roxio Easy VHS to DVD package. Suddenly, I start getting only sound, no picture, when trying to capture the VHS. In the meantime, I bought a new XPS 17 9730. Same issue - no picture, only sound, when trying to capture the VHS. I attempted to update the Roxio software/drivers, but the Roxio update site appears to be permanently down, so I ordered a new video capture card from Amazon that had great reviews. However, I still only get sound, no picture. I swapped out every conceivable cable/connection with no success. I connected the VHS player to my television and it worked great - picture and sound - so the issue must be with the laptop video drivers. I then connected to my wife's old Win 10 Surface computer, and the connect is perfect - I get picture and sound. The issue must be the drivers on the XPS, right? Both XPS machines have Intel and NVIDIA GeForce drivers. Is this something I can expect Dell to fix, or is this on the manufacturers of the video capture cards? Am I stuck using the clunky old Surface for this project? Suggestions are welcome!
