    I have a problem. I am trying to copy The Godfather Part II onto a dual layer dvd. I normally use three programs: Mac the Ripper, Dvd2Onex and Popcorn. The problem is that I after I ripped the movie with Mac the Ripper and use Popcorn to select the fileset, Popcorn automatically wants to compress it. But I shouldn't need to compress it because the the size of the movie is only around 7 gigs and the dual layer can hold just over 8 gigs! What gives? I do not want to sacrifice quality with compressing it so what should I do? I also tried burning a .dmg of the movie using disk utility hoping to try and see if I could burn it in Pocorn that way. However, when I dragged the .dmg file into Popcorn it stated that it was "not a valid DVD Video image"! I am confused. I think I should be able to burn the film without compressing it. Is there a way to do this? And if I have to burn a .dmg of the disk, how do I make it valid so that popcorn will understand it?

    I don't know about Popcorn (I use Toast and Dragon Burn), but generally what you want to do is to burn the VIDEO_TS folder as an ISO image on your hard drive, then transfer that ISO image as a data file to your dual-layer DVD. You may be able to accomplish this using only Disk Utility.

    (Not sure what the difference there is between a .dmg file and an .iso file)
