Hi all, I'm turning my Taiji instructor's Mini-DV's into DVD's for him. He would like a backup, but the file size is far too large (~15 GB for the iMovie info, one of the iDVD's info is over 3 GB, another is well under 1, not really sure why). I was wondering if putting all the files for the iMovies and for the iDVD's onto an external HD would work. If we had that, could we then just hook them up to any mac with iMovie and iDVD and burn another copy? Thanks for your help.
