I purchased the Lost finale, it downloaded, then said processing file, then iTunes blew up. Where would the file be? It doesn't seemed to be filed in the iTunes library.
When it said processing, I was also watching the beginning.
That'll be the DRM.
if you can find the actual movie file, since its downloaded... you can re-add it to itunes through file>add files. it should then be able to add it correctly.
i would assume that since it downloaded, it'd be in Music>iTunes>iTunes Music>TV Shows
(don't know the exact file structure since i haven't bought any shows)
