BSplayer and vobsub

i'm getting confused with the interaction between bsplayer 1.0rc and vobsub. I have both installed and with build 800 bsplayer prevented vobsub from loading when a subtitles files was found in the same directory of the video file. Now with build 803, vobsub automatically loads itself and the result is the subs being displayed twice (one by vobsub and one by bsplayer).

How is this intended to work ??

Which are the correct settings for both bsplayer and vobsub ? Do i have to disable one of the two ? which one ?
If I disable the subs in the bsplayer options menu, do i also disable vobsub ?

thanks
