Hi Kippycat and welcome to the forums.
The forum you originally posted is for AnyDVD which isn’t free so I’ve moved the thread for you into the main Movie Copy Software forum to enable discussion of other software.
As you’re looking for free software then I’d recommend ripping the disc using DVDFab.
If it’s a single layer disc then you can burn straight to a normal blank DVD using ImgBurn.
If it’s dual layer you can then either burn to a dual layer disc or compress with DVDShrink to fit a single layer blank DVD.
All the software mentioned is free and if you’ve any further queries please ask.
