The previous post is correct.
I ripped the Dark Knight on a PC using DVDFab HD Decrypter 5.1.2.2 found at http://www.dvdfab.com/free.htm
(I actually used Parallels on my mac to do this). Then I used HandBrake to rip the DVD.
Works perfect!!!
This worked perfect for me too!! Great idea for whomever came up with it. Worked flawlessly!!
