ImTOO DVD to iPad Converter is a DVD ripper and video converter. The application allows you to convert your DVD movies into formats that can be played natively by the iPad. Those formats are H.264, MPEG-4 and MOV. There are other audio formats also supported, just in case you want to rip only the audio track of a DVD movie.
This DVD ripper by ImTOO has a great interface, shared by lots of ImTOO converters and rippers. It has every little feature that you might need right there on the main window. There is a video player for video previews and at the bottom of the screen, you can find the profile options. There you select the formats you want to use for your output files.
I tested this app with a TV episode DVD disc, which contained 4 different titles. For each of the titles I was able to select a subtitle and if there are multiple audio tracks, you can choose the one you want. The ripping process went smoothly for me, and the result was an H.264 file that played great on QuickTime and iPad.
There are lots of advanced settings and features, like shutdown options, processor monitoring and GPU acceleration.
