neither XBMC nor Boxee importing movies

On both XBMC and Boxee (and both are updated to the latest versions as of this post), I can drill down thru my networked volume hierarchy to find movies, which do indeed play, but on neither app does Movie importing appear to work.

On Boxee, I get the Media is “waiting to be rescanned” message… but it never happens and my movie count is stuck at zero.

On XBMC, I am getting false matches (Ernest Goes to Camp is apparently one of the marquee items in my collection) and folders appearing repeatedly as movies (e.g. “U to Z” is displayed over and over as a movie choice).

On both apps I have attempted to clear the library, but this does not seem to help.
