iPad's don't have USB in. I do use that connector to watch digital copies of movies on the TV from the iPad but it has to already be loaded on the iPad. It wouldn't be able to read from a USB stick.
To the OP, you're either going to have to convert the movies back to disks, or have some kind of computer(or tablet) on hand to play the files. If you're adventurous, you could pick up a Raspberry Pi (Raspberry Pi
) and use it to play from USB direct to the TV, but in reality a netbook would probably be the easier choice.
