I also found this movie quite a challenge. Had an Interactual Player option. I also found 3 Main Movie choices. One an interactive kind of info version of the film, (title 35 I think) and the other 2 versions, (titles 34 & 36) I think were the unrated and theatrical versions. Main movie movie mode seemed to choose title 35 as default and was of little use without the menu. 34 & 36 main movie were ok. I did my Main backup to a DL disc using clone to an ISO then to the disc.

I could be wrong on some of these points as it's been several hours ago and it got very confusing.

I also had a chapter 8 freeze problem somewhere in there.

My clone came out fine.
