iTunes can't change tag info for imported movies, then permanently corrupts them!

    hi all,

    (i'm reposting this thread from "mac basics")

    i have the latest version of itunes running on the latest version of snow leopard on a reasonably decent late 2007 intel imac core 2 duo. i even just upgraded the ram to 4gb and everything.

    oh, and i just reinstalled itunes to try and combat this problem but it still happens.

    however, i have a big problem with the latest version of itunes (this might have happened previously, i am just only now using itunes for videos in a big way since just buying an appleTV). basically, what happens is this:


    • imported .m4v videos edited with MKVTools transfer in okay and can even stream onto the appleTV

    • however, if i try to change tag information for them, itunes freezes indefinitely and i have to force quit it.

    • reopening itunes takes AGES on the "checking itunes library" stage

    • i can now change the tag info fine, but the file is permanently corrupted - unable to play on the appleTV, itunes or even VLC. i can't even get any useful streams out of it from MKVTools.

    obviously this is infuriating for the files i've lost already, but it's most annoying going forwards. i want to build up a library of movies, but don't want them to be all tagged incorrectly etc.

    oh, and this issue doesn't appear to happen with .mp4s converted with handbrake, by the way.

    help appreciated!

    That's odd. I used to have this problem sometimes, but since the latest iTunes update the problem hasn't occurred. The only advice I can really give would be to use an external metadata editor. I use iDentify to enter most of the data and then go through Subler for the chapter marker thumbnails. Also, when this did happen, which wasn't very often even when it was a problem, I'd just use time machine to get the file back and then redo everything.

    yeah, i read about subler earlier. was going to download it and now you've reminded me, thanks.

    i don't have enough space to back up my library on time machine at the moment, which is super annoying, but i'm waiting on a terrabyte external hard drive at the moment, so that should all change soon.
