It started a few months ago but I never really cared. But it did work just fine
Say I have 20 music videos on my ipod, In the menu, it shows them all, If I push 1, it plays that one just fine, if i click 2-20, it goes to a blank ipod interface and does nothing.
I have reset the n4, formatted the ipod and started fresh, and than reloaded.
If I pull off the ipod and play it in my hand, it plays all the videos fine.
