Try downloading Soundflower for Mac. Once you have the dvd ready, pause it and then do the following.....
Go to system preferences and click on Sound then select Soundflower 2ch for input and output. Open Quicktime player, hit File, select new audio recording. Press the red button/record on the quicktime player window and play the dvd (make sure your mac's volume is turned up full though). Once you've recorded the dvd under File in QT you'll need to Save and name the quicktime audio somewhere. Once you're all done go back to System Preferences/Sound and reselect Internal speakers and Internal Microphone so you can listen to the QT recording.
Please be aware this works but you can't listen to the recording until you've finished recording it. Hope this helps you out.
"I love being there, I love America, I love the feeling of the wide open spaces, I love the deserts, I love the mountain ranges, I even love the cities. So having fallen in love with America over the years that we've been there on tour, I then had to 'deal with' America and the way it was affecting me, because America's having such an effect on the world at the moment. On this record I had to deal with it on a political level for the first time, if in a subtle way."

Although instrumental, the song '4th Of July' was recorded on the 4th of July, it is about how they felt that day. The Edge was playing the guitar, completely unaware that Brian Eno (one of the producers) was recording it.
