"It may also help to make sure that any AV software you have is configured to ignore your media folders and the iPod."
I'm really not tech savy so could you exsplain what you mean?
As for letting it get too hot I left my iPod in the car one day when I was going swiming.
I finally figured out the problem with it (at least for now) I was so fed up I made a copy of my iTunes library and put it on an HD so I could open on my PC (laptop) and tried to sync, it didn't work, even after restoring it to work with PC (it said the songs couldn't be synced becasue the computer need to be authorized, even though it was authroized.) So I went back to my Mac so I would at least have my music and I didn't have a $380 (what I paid years ago for my iPod) paperweight. It synced everything. I have all my audiobooks, my music, the few music vids I hadn't been able to have on it since I first started having issues.
