From the developer:
DVD Demuxer for Mac OS is an ideal choice if you need total decompilation or extraction of any data from DVD. You need to specify the input source DVD (file VIDEO_TS.IFO) and an empty output folder. As a result, the target folder will contain all data files from source DVD in the following formats: M2V, M1V, AC3, WAV, DTS, MPA. Subpictures will be extracted as a list of BMP files and a SON file with start times and durations of the subpictures.
