I'm having trouble backing up GI Joe. I think it may just be a matter of knowing what title sets to "untick". Any suggestions?
Play it in a standalone player or a software one like Power DVD and turn on the on-screen display. That will tell you the correct title.
I did that and it looks like title set 10 is the right one. Now do I simply uncheck everything except that title set?
Not sure if this will work as I don't know what version you are using but you can try this.
For Full Disc Untick 1, 3, 4, 5, 6, 7, 9, 11, 12, 13, 14.
Movie only be sure that only titleset 9 is checked to be backed up.
