Ahhh ONE OFF airings like on the History channel. I understand now! Sorry about that.
Yeah, this is mostly an issue with Gracenote. It just can't process those as movies at all because to them, it was a TV show. Something like TMDB totally can, because a lot of those are in its database.
If you feel like it, you can try dumping all those files in their own directory and adding them as a Movies import. They'll all fail probably, but you should be able to Fix Incorrect Match and use the new TMDB scanner and I bet it works.
It's a lot of work just to try to see if it works, so I understand if you don't do it. But if it worked, I think you might find them scanned in as movies a LOT better. We might make the TMDB scanner a little more useful in the future to help with stuff like this.
