Aspect ratio not right.

[Scream]

Later add:

I've forgot to specify that the aspect ratio is just fine, if i run the program right after installation.

But if a movie requires a a smaller width, and an exact height, when I click the "A" button(to change the aspect ratio), it never gets it right(tried with 4:3, 16.9,anamorphic,original), and as a result, the movie is overlapping my screen, so I can't see a part of the movie.
Which, as you can imagine, it's quite frustrating.

I must mention that I have no problems with the aspect ratios in other players.
Just in bsplayer.
