Spanned iTunes movie artwork missing, even when spanned disk is mounted?
I have a pretty massive iTunes movie collection, and I have started spanning the older ones onto an external disk as I run out of internal space. The problem is, however, that the artwork of the spanned movies disappears.
I think is to be expected when I run iTunes without the external disk mounted, but even when I mount the spanned disk and restart iTunes, they still do not appear. Everything else works fine, I can open and play the movies, and all the other metadata survives, but they all have the default grey artwork icon.
I can recover the artwork manually by simply selecting one such movie at a time and opening the "Get Info" window (within which the artwork remains) and then closing it again, but with a library the size of which I'm dealing with, this is not an acceptable solution. This method does not work when selecting multiple items.
Any ideas, am I missing something?
P.S. This is iTunes 11 and TuneSpan 1.0.4
