Problem with syncing Ipod Nano - Won't let me add films (Urgent help needed)

[mattandbenny]

So i go on holiday tomorrow, and am trying to add some films to my ipod nano. All are mp4 files and have been added to my itunes fine, but it won't let me add it to my ipod.

As you can see from the images below, i have the 4 films ticked in itunes. However, soon as i click 'sync', they dissappear from the purple bar at the bottom and the ipod syncs without them. Does anyone have any ideas? It is driving me insane!

Are they HD or standard definition?

I believe that you can only sync SD movies to an iPod nano.

I'm not sure - possibly. However the inbetweeners episodes i put on my ipod last year (and have watched many times on my ipod), now won't sync either. So i am worse off than before i started, as now the films part on my ipod is empty
