I am trying to load/sync videos from my external drive thru iTunes (PC laptop). I followed instructions on how to do this but when it comes to the part where i tick 'Sync Films' there arent any 'Films' to choose. Where are the videos? I can't browse for them or anything. Is that because they're on external drive? Do i have to copy videos to the C drive for iTunes to see them? I can load photos ok cos they're in my C drive.
