Looking for the most compatible discs for my recorder and they have to DVD-R or DVD+R Dual Layered. I already stopped using 4.7 gig discs. They don't hold enough video
Dual-Layer disks are picky. Get several brands, and find out which works with your laptop and authoring program.
In my case (2012 vintage Dell laptop) most of well-known brands (Memorex, Verbatim) refused to work, but a cheap WinRite do.
