Hi Steve
I use 1 Click DVD copy to put the files on my PC. It creates a .VOB file with VTS_01_1 etc.
As I said, I have done this many times before without problems - maybe the copyright protection has improved! I think I'll have to admit defeat. I could download it from iTunes for a reasonable cost or just wait for it to be on TV again.
Many thanks again for all your efforts.
All the best
Geoff
