digital version to transfer? I am trying to add the digital versions of my kid's movies to iTunes to be watched on an iPod during a trip. Most of the digital versions have been on a separate disc and have been no problem. Alvin and the chipmunks: chipwrecked is one disc for both DVD and digital copy. I have the disc in the optical drive but the DVD version opens and starts playing the movie and I can't get to the startup of the digital copy transfer. It seems I need to do something manually but I don't know what is the first step. Any suggestions? Thank you.
