hi guys i have ripped The Shield Season 5 with handbrake, i used the itouch/iphone template but also added the commentarys as the second audio... i have watched the series and now i would like to just listen to the second audio track on my ipod shuffle. how do i demux the .mp4s? i have tried a couple of methods but they only leave audio #1 behind. thanks KYUSS PS. i don't know if this is the right section for posting this?
