Has anyone else have this problem? It just happened to me today after a 50 minute drive, the ipod started to stutter then just stop. I thought it was something wrong as it would not even turn on, comes to find out it was out of juice. I have the cable that I bought from Best Buy for $50, and have been able to play videos and music on the 120 no problems. I was under the impression that it charges the ipod during play, what gives? When I plug it back in later tonight I saw a charging picture on the ipod, so not sure why it would drain the ipod during my drive. Anyone else had this problem?
