Another CloneDVD newbie in trouble!

I have recently installed CloneDVD 2.4.5.4 along with AnyDVD 3.9.4.2.
Each time I try and backup a movie DVD, at the end of the ‘Creating DVD files’ run, I get an error message 'Write to video media was not successful, Showing an error code W2.
This happens even if I Clone the DVD keeping all scenes/Audio in full.

Any help would be greatly appreciated as I trawl the forum once again.
