Sean recently bought a Water Wolf underwater video camera for fishing. He'd like to be able to import the video he takes with the camera directly to the iPad. Leo says to get the Apple Camera Connection Kit. That will allow him to plug the camera or SD card into the iPad.
Even though the camera records in .mov, not all .mov files will work on the iPad. It could be a non standard .mov compression that's having issues being read by the iPad. He could try using a different app. VLC is a great option. He should try installing that, launching it, then plugging in the camera to the connection kit. Maybe that'll solve it.
