movies will automatically organize alphabetically in the actual finder, no way around this but not too important as you access them through itunes anyway, within itunes you can change a lot of meta data by right clicking and selecting get info, you can use this data to make smart playlists of generes etc, i would also recommend an app called MetaX that will add metadata to a video (or group of vid like a whole tv season) before you stick it into itunes.
