iMovie won't import my Videos!
Need some help with iMovie. Converted a number of .avi files on my PC to mp4 format suitable for iPad3. When I open iMovie it says that I have no videos but if I go to Videos app I have heaps of video/movies/podcasts. Location services are turned on already so not that. Videos aren't appearing in camera roll or iPhoto either. Any advice to get these clips in so that I can create a movie would be much appreciated.
iPad (3rd gen) Wi-Fi + Cellular, iOS 5.1.1
