iTunes -48 Error when syncing iPod

[Scythe]

Hi, got a problem with my iTunes. Whenever I plug in my iPod, it attempts to sync it but a error appears saying It can't copy, error -48.

Now, I know that it isnt the ipod because it worked fine on (dare I say it..) Windows. The first time i plugged it in my mac, this error showed up .

If i click OK on the error, and then press Sync manually, it works? Just it won't sync automatically when I plug it in

Any Ideas?

Yeah I have, I restored it and found out that there was a new firmware so i installed it. Still got the problem

By the way, I have a iPod Video 30gb if it helps
