No it is not broken links, they are not their period. Yeah i think iTunes thinks that i already own those films for some reason and i can download them again because it cant see them in my library.
If they are not there period then you have to add them yourself as I have said twice already.
iTunes is picking up your computer authorization and AppleID login into the Store and telling you you have content not in your library (the database iTunes uses, not what is actually on your computer as files which iTunes completely fails to see). It is showing you have content to download.
I think it may be to do with where the ITuned Media folder is directed to in the preferences. I just checked it and it seemed to have changed itself to an Itunes folder on my local HDD, not my network drive.
I tried to change it to the root folder in my network drive, but it still hasn't populated the media into iTunes ...
Changing preferences will not get iTunes to inventory the media folder. Changing preferences simply tells iTunes that is where you want ot store any new media added from that point on.
I'm not sure if the file directory is correct. My root folder on the network drive is named 'iTunes Library' within that folder I have music, books, movies folders etc, but there is also one named 'Itunes Media' with an 'automaticaly add to itunes' folder inside that, but that same 'automatically add to itunes' folder also exist within the root folder...
Its like it thinks all my media should be in that iTunes media folder, but its not, its in the top level folder above that. You would think I should just be able to point ITunes at that folder...?
You have residual pre-iTunes 9 media structure as well as the new structure. If everything was working I'd tell you to consolidate/organize to update it all. As it is since you will have to add all media to your new library it should do it anyway.
