I made a backup last night of Gridiron Gang (R1) using AnyDVD 18.104.22.168 beta & CloneDVD2 22.214.171.124. It works perfectly.
I cloned it [preserving menus] but I left out the following titles: 14, 15, 19, 2, 16, 20, 12, 13, 18, 1, 17, 8, 41, 5, 9, 10, 7 & 11. Yeah, I didn't put them in order and this is the order they showed up in using CloneDVD2 and the order I removed them from CloneDVD2. Since it was brought up before, I did not use the Jump Directly to Title Menu feature. I never use that.
The titles I removed were either trailers for other movies, the FBI warning, 0 second titles with no audio, or short titles with no audio and just a black screen for a couple seconds. Basically I left out the junk but still have a disc with the short Sony intro, menus, the movie (duh!), bonus features, extra angles, etc. When the movie ends it goes back to the menu.
