Anyone use this to convert blu-ray movies to iPad 720P video? Can it really rip any blu-ray? Is the quality of the converted video noticeably better than a standard DVD? I've been really disappointed with the availability of HD movies on iTunes so I'm looking to put 4 HD movies on a 16GB SD card to load to my iPad via the camera dock. I have about 10 of this cards already so I figure this might be a very portable way to carry around 40 of my favorite HD movies.
