Best way to organize videos?, Using tags Options

[kevinmd88]

I'm new to WDTV and I love it... but as with any newbie trying out a new gadget I have some things I can't figure out.

For me, properly organizing my media is excruciatingly important. I have an external hard drive coming soon, but for now I'm settling for using my desktop computer as a media server. I access the videos (which sums up movies, DVDs, TV Shows, music videos, and the like) by going to the Video menu -> Media servers -> (computer name). This brings up the following options:

All Videos
Video Genres
Video Actors
Series
Rating
Video Playlists
Folders
Recorded TV

Most of these are pretty easy to organize by, in that WMP12 lets you edit the fields... but for the life of me I can't figure out how to tag my TV Show videos for the "Series" section... WMP12 doesn't seem to have a field for this, and I've tried a handful of tag editors but couldn't find a way to set this data.

Can anyone guide me through this?

On the same subject, is there a program out there that will let you edit your media file info specifically for use by the WDTV?

Thanks in advance for any help.
