Your best bet is to search for instructions online, which will probably do much more for you then one of us trying to type out an explanation.
I use a combination of DVD43 and Handbrake to rip and transcode the DVD, then in iTunes you need to import the movie. File->import file (or something to that effect). Then just set it up to sync to your iPod Touch.
I haven't bought an iTouch yet, but am going to.
Just a question: is there any way in which you can get videos from a DVD on to iTunes? If so, how?
Nice idea for a group, guys (I'm new here)!
Thanks,
