Hi, Call me naive if you wish. I updated my 1st gen iPod Touch to the 3.1.2 software the other evening and now find nothing happens when I double click the main button by the screen. It used to play my music videos on shuffle but as mp3's and not mp4's. Can this be still be done a different way please, as leaving the videos playing when the pod's in my pocket just wastes the battery life. Cheers.
