i tagged about 50% of my movies now via IMDB and it works very well. The only problem i figured out is, that with german movies, it wont work that well or you have to edit atleast the title since the titles sometimes differ from the english language.
since imdb has also a german translation (imdb.de) it would be nice if you could parse the german imdb instead of the english one.
is there anything planned on this? if not, i would try to get my hands on this since imdb supports english, german, italian, spanish, portugese and french.
