I wonder what the OP meant by:
Making a BU copy of a software program can & usually is more complicated.
If it is just an unencrypted movie the ImgBurn should rip & burn it fine .
If it's an encrypted movie then DVDFab trial would be the route to go.
After the trial is up then DVDFab to rip then DVDShrink to compress.Then burn with ImgBurn.
