I have a concert DVD I want to make into an MP3 to put on my ipod/iphone but I need to rip, split, and encode it (and I have no idea how or what that all is). I'd like to be able to do this for free if possible...I have a macbook but it's from 2006 so it's pretty old. Any help is appreciated, also, how much time do you think this would take? It's a DMB concert so it's pretty long itself haha.
