IPhone movies won't go onto my phone?

I've put them on my phone before so I know all the formatting is right but I try to put them on now and it won't transfer. It says it's downloading but then after it's done I go look and there's nothing there.

The new itunes will save movies as "home movies" so if during the sync there's no error message, go to your videos and go to home movies. Most of the time they are on there
