I have bought a Video Saver, Magix and I want to digitize VHS to my computer (Lenova). When I start a project, I only hear sound, and no video (picture). What more do you need to know?
Which version of Windows do you have? Video Saver is now an old product; its more modern equivalent is Rescue Your Videotapes. I'm not sure whether VS is able to run under any recent OS, especially Windows 11 if that is what you have.
Assuming you have correctly installed the software, it may be that the driver for the USB Capture device needs to be updated. What colour is that device and what model number, if any, is shown on it?
