My nano will freeze sometimes when I navigate to a dance music podcast that contains chapter points. Not sure how they put those chapter points in the podcast, but they look like little black lines in the timeline of the podcast.

Sometimes it would freeze as soon as i got to my dance music podcast list of individual podcasts. I had to keep pressing buttons and it finally returned to main menu.

other times, it would freeze as i tried to play a particular podcast with the chapter points in it. it would freeze when going to show the timeline playing. The music kept playing throughout though while locked up.

i had to reboot the thing twice because as soon as i rebooted first time i tried the same podcasts again. It seems to only happen on podcasts with chapter points.
anyone know a solution?
