I can't get Daemon Tools to mount a DVD image produced by Nero. Is there any way to convert it to an .iso image?

Obviously I could use another tool to directly write the .iso file, but I have two problems with the ripped files. 1. A problem is reported when the .iso tools in DVDCLONE or ifoedit try to write the file, and 2. the total file size is about 7.5 gigs. I'm hoping to mount an image so that I can use DvdDecrypter to extract just a portion of the film...which would be far easier to do than to remaster the whole thing!

Thanks!
