I am trying to take some dvd's and put them onto my Western Digital Media Player. My problem is that each episode of the show in question is made up of 2 .vob files. The second file for each episode automatically plays the directors commentary, and has to be turned off manually in VLC player. Is there a way to remove this track? I've tried conversions in VisualHub, Audio Converter, and Mac the Ripper, but to no avail.
