Place all the videos in a new folder (be sure to rename them to .mp4). In iTunes click "File" and then click "Add Folder to Library". Point the "Browse for Folder" window to the new folder which contains the videos, high-lite it and then click OK. You will see the video names pop up in the right pane. Drag any or all the videos to your iPod name which poped up in the source pane after your iPod and Itunes started to communicate.
