I have a 10 gig iPod, 3rd gen, and it has this funky thing where every so often i will start a song and after the first 16 seconds it skips to the next song. If i go to restart the song it will do it again. If i listen to 20 minutes or so fo music and then go back to that song, it plays just fine. It also works if i sync it up. To me this is sounding like a cache issue because whenever that song gets cleared from the cache and then reselected it works fine, until a little later it happens again. I have yet to figure out a pattern to this occurence except that it has only happened to songs i purchased from the itunes store, which i find intriguing. Is anyone else having this issue and does anyone have any suggestions on how to take care of this?? I bought it at the end of september so the warranty is still good.
