Hey, I had the same problem, but i couldnt get songs on either...
if you cant get songs on do this... worked for me but im still stuck with movies...
Disconnect your iPod, close iTunes. Remove the iPod from the dock, open "My Computer" and leave the window on a visible spot. Place the iPod on the dock. Check if any new removable drives appear. If it does, keep reading. If not, then I'm afraid I can't help you. Now that we can see the iPod drive, open iTunes. POINT OF RESTART Put the new songs you want, as much as you want, or delete the old ones, do something that trigger the automatic syncing by iTunes. The software will try to sync, and it probably will show the same problem as before. Don't panic, everything is fine, don't use CTRL+ALT+DEL, please. Just close the window displaying the odd message when it appears. Leave iTunes open, displaying your iPod content. Go back to the "My Computer" window. Leave it on a visible spot. Now let's start the magic, go to "Start" -> "Control Panel" -> "Add New Hardware". Click on "Next". You will see your iPod drive reappearing on the "My Computer" window. Just return to the iTunes window, click on "File", "Sync iPod" and it's done. After syncing, the iPod drive will disappear from the "My Computer" window. To sync again, repeat the operation from the point of restart. To eject your iPod, do it as you would do on a normal operation.
Hope this helps and if anybody finds out how to sync movies please let me know at cameronwhalen@hotmail.com
