I just recently discovered this great tagging software for adding the meta data to iTunes video's. The software is called iDentify and runs on Mac OS X and is free. The great thing about this software is that it automatically looks up and pulls down the information for the Movie or TV show that you are trying to tag so you don't have to type a thing. It even grabs the album art. So, if your looking for a way to automatically populate the tagging information for your videos I highly recommend you take a look at this program.

Some other software that I looked at:

	MetaX - Free to use and a ton of features, but I couldn't find a way to have it auto populate the tags.
	Subler - Free to use and it can auto populate, but it only reads from TagChimp and some of the TV Shows that I am trying to tag didn't exist on the site. However, if your looking for a application to use with Applescript, this works great with their commandline version.
