Adding artwork to movies in iTunes not working

[pedz]

I have about 140 movies in my iTunes library and i usually open the 'get info' window and past the movie poster into the artwork tab. it has worked for all of my movies but recently it has stopped. I paste the artwork and click ok, it pauses as though it were updating the file but never actually updates it. In the library it still has the first frame as the artwork.

I have used atomicparsley lately to get around this but the two latest I have are very long and atomicparsley actually says it cannot tag files that size.

Has anyone experienced this and know what I can do to get it working again, not sure what changed???

Any help is appreciated.

it happens to me every once and a while too! its as if the file artwork is locked. theyre mpg's that are doing it for me. i just downloaded the whole series of a tv show...it took forever. and now i cant even add the artwork to it because its just showing the stillframe.

someone's GOTTA know whats wrong here....
