Ok, so I have created two iMovie projects...lets call them A and B I was working on project B and imported A into B. Now I am wanting to shorten the length and edit out quite a bit out of project A and it says I can't work on it in iMovie as the folder is locked or priviledges, etc are wrong. I have check for locked folders and priviledges are fine. Is it this way so I don't mess up project B which is using project A? I would like to keep movie A in its original long version and make a second version that is much shorter...what is the best way to get myself out of this mess and do what I want. Second big question: I have also already saved a iDVD project using B (which includes A) but want to include in it the shorter project A when I get it edited down. How would I go about doing this. I have the dvd menus, etc just the way i want them and would like to not have to recreate them. Also, would my chapter markers be changed if I shorten the project A movie? PS I am using the latest version of both iMovie and iDVD.
