Sync Only One Season of a TV Show to Your iPod

I’ve had my video iPod for a while now and I’ve amassed quite a collection of some of my favorite TV shows, but I’m running into a storage problem. I have multiple seasons of these shows, but I only want to sync the current season to my iPod. Unfortunately, when selecting what you want to sync, iTunes only gives you the choices to sync x amount of “selected TV shows”, “selected playlists” or “all TV shows.” Why can’t I just select TV shows by season? I hope they introduce this feature in the next version of iTunes. In the meantime, the following are the workarounds I’ve found for dealing with this shortcoming. Let me know if you have any better suggestions!

1. Create Video Playlists: On the TV Shows tab, you can change it from syncing “selected TV Shows” to syncing “selected playlists.” This requires a little manual labor, since you have to build your playlists, so the best way to do this is to use the “Smart Playlists” feature. Go to File –> New Smart Playlist (or Ctrl + Alt + N). Change the first drop-down box to “Show”, the second drop-down box to “is”, and the third to the name of the TV show you want (it will even auto-fill as you begin typing.) Then click the plus sign (+) to the right of this third field. Now you can add more conditions. Change the first field here to “Season,” the second to “is,” and the third to whatever season you want to sync. Click “OK”. Since “Live Updating” is checked by default, unless you uncheck it, the playlist will auto-update as new shows from the season are downloaded. Now you can change the settings from syncing “selected TV Shows” to “selected playlists” and sync away.
2. Edit the Show tag: Another option is to edit the TV show’s tag so iTunes thinks it’s a different TV show altogether. Doing this will let you just use the checkboxes on the TV show tab underneath “selected TV shows.” To change the show’s name, you right-click on the show in iTunes and choose “Get Info.” Then, click on the video tab and edit the show’s name.
3. 3rd Party tagging programs: Using 3rd party tagging programs will let you do option #2 faster than editing shows one-by-one. Here’s some I found:
   mp3Tag: This is a tag processor for MP3, WMA, OGG, WV, APE, FLAC, WAV, AAC, MPP/MPC/MP+, MP4/M4a files. The features include an automated search for lyrics and pictures (album covers), tags import from Amazon and FreeDB, and an automatic tag filling option, which works for mp3 albums that come without tags and meaningless file names, like 01.mp3, 02.mp3, 03.mp3, etc. You can view and edit tag information, save lyrics and pictures inside MP3, M4a or WMA-files, view technical information about music files and delete unused MP3-tags.

   I don’t have a Mac, but I hear AtomicParsley is good for Mac users.

Any other ideas?
