The Power User's Guide to Video Encoding with Handbrake
Encode a Copy Protected DVD
It doesn't matter that you purchased your DVDs at Walmart and have all the receipts to prove it. Chances are, most, if not all of them, come saddled with some form of copy protection, preventing you from making legal backups or, in this case, encoding to mobile. That's unfortunate, but by no means an obstacle we can't overcome.

The easiest way around this is to install an on-the-fly DVD decrypter. DVD43 (free, www.dvd43.com) does a decent job and it's free, but it only works with Windows Vista 32-bit, Windows XP, and Windows 2000. That means it's not an option for anyone who's rocking a 64-bit version of Windows 7.

Another alternative is SlysSoft's ever-popular AnyDVD (price varies, www.slysoft.com). Like DVD43, AnyDVD works in the background, only it's continually updated. There's also an HD version which works with Blu-ray HD-DVD media. They're a bit pricey (about $115 for a 2-year license, or $158 for a lifetime key), but worth it if you rip a lot of movies.

If you want the best of both worlds (free and robust compatibility) and can do without on-the-fly encoding, DVDFab HD Decrypter (Free, www.dvdfab.com/free.htm) gets our nod of approval. DVDFab supports everything from Windows 2000 on up to Windows 7 in both 32-bit and 64-bit flavors.
Start by opening up DVDFab and selecting the proper Region (if your DVD isn't automatically detected, click on the Source folder and point DVDFab to your optical drive). On the left-hand side, you'll notice a sub-heading titled File to Mobile with several preset options. These work well, but they don't have the same level of customization as Handbrake.

Expand the DVD to DVD option. If you're only interested in the main movie and not the all the extras, select Main Movie. Click the Folder icon next to the Target field and select a destination on your hard drive. Click Next>Start.

DVDFab will proceed to strip out any and all forms of copy protection from your DVD. When it's finished, open up Handbrake, click Source, select DVD/VIDEO_TS Folder, and point Handbrake the location of your decrypted files.
From here, you just use Handbrake like you would with any other video file. Select from a preset on the right or customize your own, and hit the Start button.
