grey movie...
 

can anyone explain how come i see a grey picture for some of the movies i play in BSplayer? (by the way, i get the same problam playing them with windows media player but not with divX player)

Probably it's div3 problem. Open the movie and go to filter configuration. You should see here some sliders. By default they are at 0%. Move them in a medium position.
Or, install DivX 5.11.
