How To Copy 2 sided DVD

I am trying to backup Goodfellas and 1/2 is on one side and I must turn over the disk to backup the rest of the movie. How can I record both sides to one disk?

I’m using CloneDVD and AnyDVD.

Thank You

You can use DVDShrink/AnyDVD to rip and combine both sides, then burn with imgburn.
