I did that, and after CloneDVD scanning the DVD, the quality only shows 4%...
Yes, I also did this, but I needed the menus, because this is like a book, where I need to select which chapters to read. Unlike movies where it is ok to watch the entire play. But this is like a book, that if I wanted to read a different chapter, I need to go to the menu and select the chapter(s) I wanted to read/watch.
I bought this DVD like 7 years ago. And I am noticing some degradation of quality, so I wanted to make a back up just in case. Seems I'm not going to be able to back it up, because CloneDVD is not compressing the files to fit into the 4.7 gb disc. Don't know why because it does the other DVD's.
