I don't know which version of iTunes tu got, but on 11.0.1, tu can access your ipad por clicking the 'iPad' icono on the parte superior, arriba right corner, which will automatically open a window of iPad options. tu should find and open the 'Movies' menu and mover your video there. When your video appears, tu tick the box siguiente to it(or just tick 'Automatically include all movies') and sync your iPad again. This should help.

This one is free, and does require actualización but it works really well. Then you'll need to convert the files to MP4 with the converter, to do this click "Add Videos" then select "Video" under output type, and select mp4. siguiente tu will go into your computer's "Music" folder and select iTunes, then under iTunes select " iTunes Media" under that select "automatically add to iTunes" copy and paste the converted files there and they will automatically be placed into your iTunes "movies" section.
