Something I've started to experience on the iPhone 4 and iPad is the lack of my videos, songs, and audiobooks showing up on the device. They are physically there, but the "No Content" bug rears it's head and you can't play anything. This is really starting to irk me. Does anyone know of a work around? I've found a lengthy discussion of this rather severe problem in Apple Discussions and it seems to be centered on iTunes 9.2. Tried everything including complete RESTORE and sometimes they show up, sometimes they don't.
