Good evening d_deweywright, I did as you asked, it would have been plausible, to have connected the hardware before installing it.
So, I took it all over from the beginning, while uninstalling the program as indicated on this post ( https://forums.support.roxio.com/topic/90967-no-video-signal-when-trying-to-use-easy-vhs-to-dvd-plus/#comment-539008 ) then I reinstalled in Windows 10 version in administrator mode, taking care to close my AV, firewall, disconnected my internet, closed MalwareBytes. All this to reach the same conclusion ‘’ No Video Signal ’’
I'm still waiting for a tip to solve this problem, which exasperates me at the highest point.
Thank you, but it didn't work. Another little try ,,,
