You should also investigate managing your synchronization via playlists. If you created a playlist that contained the music and music vids you wanted to have on the AppleTV, you could move stuff in and out of that playlist any time, and the next time you sync, the ATV will pick up the changes.

Playlists for music can be explicitly set to sync vids as well as music, so I think this is exactly what you are after.

The key though is to set the AppleTV to manual sync so you can pick and choose which music playlists are getting synced.
