This topic is pointless as far as I'm concerned since some people don't have AnyDVD. Try backing up the disc without AnyDVD running.
Get Rich Or Die Tryin,.....has nothing special on it, just the standard encryptions surprisingly considering how this movie was poorly boot-legged. One should be able to back up a copy using the traditional decrypting software programs be it free or otherwise (I personally used AnyDVD and SHRINK W/NERO Recode 2).
