I've noticed that a lot of space (nearly 20BG) on my iPad 2 is filled with video files even though I have disabled syncing for movies, TV shows, podcasts and iTunesU. Does anyone have thoughts on where this may be coming from? Could these be temporary Netflix files? I wanted to free up this space so it would be available to upload photos from my digital SLR on an upcoming trip, but I can't seem to get rid of them. Any ideas would be appreciated. Thanks!
