Well, I had to send back my 30gb 5th gen iPod around Christmas, so they sent me, what I think is, a brand new/ refurbished iPod...
Now, I have two questions. When I try and sync it with iTunes, it will sync stuff I put in recently, but some old stuff won't sync. I have 2 programs for downloading, I don't know if this would affect it, most of the stuff that doesn't sync is from the old one, but I still want it.
And, when I do sync it, it says there is 6.77 gb of "other" content on the iPod... how do I get rid of that?

the other is the space that the format/layout of the information on the iPod takes up.
though im not sure about your other problems.
