3 hours is not normal for 250 megs, so something is wrong. The synch error backs up this assumption.

Were you using version 1.03 of the software to do your upload? If not, read this.

If you still get an error with 1.03, check here for information on synch errors.

Incidentally, your error was a "Connection Timed Out", meaning the player software locked up during the upload. If you were using Beta software to do the upload, that would explain it, and you need to go back to 1.03 to do your big synchs.
