The Apple nano 5th generation nano wraps it's video in an AVI container that plays on the iPad using the photo app. I just imported a few video into the iPad with the CCK from a nano and they play just fine. I haven't looked at the codec that the nano uses...
As stated above the AVI container can have many different codecs wrapped into it. You need to 'get info' on the video to find out which codec is being used. Your video player on a desktop computer should give you this info.
