can't manually manage with 80gigvid

I can't manually manage with my brand new 80 gig ipod. Every time I select the option, I click apply, and itunes says that it's updating my ipod, but it doesn't say anything on the ipod itself. After a while, itunes will just give me some BS about an unknown (-50) error, and there ends up being no change. I can't manually manage songs/videos.

 

Never encountered this. Some results from search engines:
