Still in FullScreen mode i see the border
 

GRR!
The annoying bug is still present in the 1.0 final version.

I have set that when going in FullScreen mode BSP changes the resolution to 640x480.
And when I switch to FS i can see the top and the right side of border. Actually it's transparent border, i can see my desktop in it.

I have WinXP, SP1, all fixes, Amd Athlon 1800, Windows classic skin(in windows, not bs). But I know that it's BPlayer's fault not my computer's.

You're right; I already reported it by mail.
You can use "Borderless play window" like me as a (temporary) "workaround".
(rightclick > Options > Preferences > Video > "Borderless play window")
