If you had the problem with iTunes 8 or later, ever since iTunes sorted Music Videos under music, that your music videos state "Unknown Album" under the album name then I got your problem solved. All you have to do is hit the get info for that specific video and go to options, under media kind pick, MOVIE. Make sure the Album name is left blank, then when you go to your movies, do the same thing but change the media kind back to MUSIC VIDEO, and presto. The Album name is blank.
This seemed to be a iTunes Glitch.
