In case you're not even at the stage csimon is starting from:
In Standard View (list like), right click on any column heading. Make sure that the [series] field appears.
Then select your video files.
Right-click on the [series] entry for that file and select Rename.
Enter War and Rememberance.
Do the same for [Season], but enter 1
Do the same for each [Episode] entry too, but enter the episode number manually. If they appear in the correct order already, simply select them all, right click in the top [Episode] entry (which is probably blank) and click rename. There enter this:
=Counter(1)
That will enter 1 under [episode] for the first file, 2 for the second, 3 for the third and so on. You should now be able to do what csimon suggested.
You should also make sure that the [Media Subtype] shows TV Show. Sometimes MC guesses on the media subtype and will choose Movie if a file's duration is longer than most regular TV shows.
