I also have POPCORN, but I'm experiencing a big problem writing backup. Since Mac dvd backup software is pretty limited, there's not that much of a choice. And the ones the are out DVDZone2One, doesn't work write. Popcorn seems to answer that but it's given me a "buffer underrun" message quarter way into the burning. And as far as I can tell disc burned from Popcorn is in file form, not auto play like a normal DVD. Has anybody else experienced this with Popcorn? I use DVD Backup to import the movie to my hard drive (it gets rid on the css encryption and region), then use Popcorn to compress and burn it to disc. But like in the past, compress and burn with Mac software is frustrating, because nothing works as easy as PC (so far). Ranting: And why does Elby put out CloneDVD2 for Mac in Japanese and not anywhere else?!! I know there is a big Mac population in Japan, but come on, what are we, chop liver?
