.m4v file icons have become solid white in Lion Finder under iTunes 10.6.3

Hi there,

I'm making this a dual category post, since I cannot determine whether this is an iTunes issue or a Lion issue.

I discovered that after updating iTunes to 10.6.3, all Finder icons for file container type .m4v have changed from their standard iTunes "notes" icon (with "M4V") to a simple white icon, regardless of the Finder view set. (Icon, List, Cover Flow)

All other iTunes-related icons are fine (.m4a, .m4r), as well as icons associated with other applications - it is limited to .m4v video files, as seen in the below Icon view screenshot:

My thread in the Lion forums, including actions already taken to attempt to repair, is found here:

Has anyone else noticed this, or am I alone in experiencing this anomaly?

Thanks!

Steve
