ripping dvd commentary and using dual core with x264

wanted to rip a movie for my psp and have the audio commentary. found http://ubuntuforums.org/showthread.php?t=273635 which helped me remember one way to view what audio tracks are on a dvd:

mplayer dvd:// -v | grep "audio stream"

there's a way to do it w/o displaying the video too but heck, time is scarce these days and this did the trick.

then i just used the steps outlined in a previous post and specified the audio id instead of the audio lang (i also tried using multiple threads to see if it was still acceptable quality with a speed bump):
