I just tagged a bunch of TV Episodes, and didn't see the problem. Does it happen all the time now, or just this once.
Also, I don't know if you've seen the post I did in the MetaX forum. I'm going to start charging $9.95 for MetaX, because I just didn't get any donations. But I don't have any plans to charge for MovieLibrary, as I don't have that many people that use it.
Anyway, let me know any more details (does it just happen with movies, or do you see it with TV as well), does it happen all the time, anything else that might help.
