While I still have to finish my HOW-TO on duplicating DVDs (hmm), this product struck my attention: Fast DVD Copy.
An all-in-one-one-click commercial app that duplicates your personal DVDs - and commercial ones for that matter - switched them to region free (and presumably disables Macrovision).
For USD 99, version 2 allows you to select the bonus you want - or don't want for that matter. The previous version duplicated the lot, limiting to a maximum of 97 minutes the movies it could copy. Apparently, this has been addressed in the latest version.
Beware of the licensing scheme - install it on the computer that will be used to duplicate:
Your license is valid for one computer only. If you want to install Fast DVD Copy on a second Mac, you need to buy a second license.In addition, your Fast DVD Copy license is computer-specific. Your serial number will only work on the Mac that you licensed it for.
