I noticed recently that DEBUT would not record any shows on the CBS network! Recorded the ads fine.
Checked and found all other sources recorded OK.
CBS has some kind of technology that "blacks" the screen.
But I got around this. I went to a library and used the free version of Debut. On a Windows 7 computer!Worked fine!Plays back on Windows 10. Kind of a hassle,but if you really need the show,then….
I'm using a Windows 10 computer normally.This post is for those who don't have a DVR,use Debut,and have a right to use the Betamax rule (time-shifting for own personal use).
