burning a .dmg in Popcorn?

[jwnulife]

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? Is there a better way to go about this?

What version of Popcorn?

Disk Utility does not make UDF-formatted disc images so it is correct that the .dmg file you created is not a valid DVD video image. The freeware app DVD Imager can do that (as can Save as disc image from the Popcorn File menu).

Popcorn might presume you're wanting to fit the movie to a single-layer disc, but as soon as you click the burn button and it recognizes there is a DL disc there it shouldn't do any compression and proceed to burn as an exact copy.

Thanks. Do you know if DVD2One can create UDF formatted disk images? I did not proceed to burn the movie in Popcorn because I assumed that it was going to compress it (The Popcorn window states that compression is at 18%). I will try to do it anyways and see if what you said will work. Maybe it won't actually compress anything once it recognizes the dual layer.
