Whats the difference? I did some experiments with DVD Clone before posting here. More confused than before
'Cloning' (including all Titles and Menus) gives me Video_TS Folder same size as original. Fine. VTS_01_0 is indeed the menu page. Write DVD, No Menu. Video plays on insertion yo player.

Try 'DVD Copy' with Preserve Menus checkbox ticked, also gives me Video_TS with Menu page inside. Write that, same result. No Menu.

Try output to Iso image and burn that with PowerISO. Still no menu.

The only tuts I can find for Clone DVD don't address this. Any ideas?
