strange problem that hasn't been fixed for me with the last couple of updates. i have been trying to add movie artwork to the files i've added to my movie library over the last few months and i can't get anything to "take". anything added prior to a few months ago is fine and i can even change those, just no movie files since. also, after i manually try adding artwork with "get info", it disappears from the artwork window in the editor when i go back in there. it's like i never tried adding it. no problem with music artwork. just movies.
