Feature requests/ideas

Hi!
I'm slowly running out of ideas what to add to vobcopy. Interesting in my opinion are (but I'm not sure that I can manage that, any help appreciated!):
-ripping the subtitles to separate file (with the use of extsub maybe?)
-extracting the audio tracks and feeding them to lame (ac3dec/a52dec maybe?)
-getting the whole playing time and some other stats about the film and putting them into a file to the film (libdvdread provides something but I'm not that good with structs yet...)
-ripping of the dvd chapterwise (had something in the code some time ago, but didn't work on the first run and I didn't understand it (was only copy/paste from play_title.c from the libdvdread-guys))
-???
Any more ideas?
Post something or mail me
