Or skip all of the "breaking encryption" trouble:
Look for a file called "wnaspi32.dll" on your hard drive. If you do not have it, download a trial version of Nero or some other DVD playing app - and the file will be included. You can also search the internet for copies.
Copy the file to the path: C:\Windows\System32
Now any DVD ripping program (I like to use ImageBurn) will rip ANY DVD no matter what the encryption method is. It simply uses the same .dll library that the system uses to decrypt & play the DVD in the first place - with no hassles as long as it is found in the above path.
Have fun filling up your hard drive!!!
