HD/SD Tag only showing after playing

Hi,

I have SD and HD movies, after scraping it dont get the info, the green HD or blue SD symbol to the right of the movie. I only get that after actually playing the movie a bit. The movies are on a samba share.

What is strange is, when I attach an USB Drive and scrape movies on that, i get that info right away without playing the movie.
xbmc has write rights on that samba share.

Is there a way to get that info for the movies on the samba share ?
thx alot
