Sorry, forgot to answer your other questions. Depending on the movie, you can use dvdd and shrink to accomplish the same task, ie., fitting a movie to a SL disc, but not this one...the decrypting capability of dvdd is defunct as of ~ 04/05...it's still a great application, but no longer developed.
Express, however is consistently updated and is incredibly easy to use, literally one click and your done...and you already own platinum. There's no reason that we can't figure this out, you should be able to rip and burn the movie ...no problem. The file size for main movie will be huge (I think), so the compression will likely be extensive....you may want to consider this. I did a bkup to a DL.
