Bought a 4g nano. What am I doing wrong? I use audiobook builder and that seems to put the tracts in the right order. But I end up with multiple copies of everything, twice on my itunes library and one on my hard drive. But the most annoying thing is if I shake ipod and it goes into a music tract, or I skip a track by mistake. Then I have to fast forward/ rewind 15 seconds at a time through a long hour plus track? How do I make it skip in 5 minute increments instead? I'm really frustrated with this nano so far. My Sansa Clip was way better for audiobooks, on that I would just hold down the forward or rewind button and it would speed up and start going super fast till released.
