Rebuilt iTunes library missing video

Tonight iTunes crashed while I was importing a file. It froze, no biggy. I force quit it and reopened it.

When I opened it, iTunes had to rebuild the library. Unfortunately once it had finished, my albums were all there, but my movies and tv shows were missing (from DVDs).

i went to the media folder in finder, all of the videos are still there, but iTunes isn't seeing them.

My question is, how do I restore them?
