What about this:

When importing a file from a folder called tv show automatically label it as a tv series. Or when importing form a folder called drama label it as drama.
Or ignore all folder names except tv series to keep things simple.

Would save people a lot of time re-tagging their collection is Boxee.

This especially pops up when you have some series with no season and episode tag (so no 01x03 for example) just the episode titles. Now they all show up as movies and you have to rename all your files to be recognized a tv series in Boxee.

On the other hand it forces you to (re)name your files properly
