i'm pairing XBMC with Ember Media Manager as suggested in the XBMC thread.
have to say, it's much better than using the built-in XBMC movie scrapper. don't have to create .nfo files and the such.

i tried mediabrowser plugin on top of win7 media centre, but there's no media manager like ember for it. and it can't read the movie info in xml format that i've set for each movie.
so now i'm sticking to XBMC for the time being
