Weird bug with 2 cds movies & vobsub subtitles

[Loul]

I've made a 2 cd divx of the godfather II.
As there are problems with bsplayer finding the 2nd cd on request, I put two subtitles files per cd : one with the same name of the avi with only the subs needed for the avi on the cd and on with the whole subtitles.

I designed properly the bsi files (with the startime option).

Now the funny thing is that when I play the movie on my hard drive with all files in the same folder, the movie start with the vobsub subtitles on (I choosed DefaultSub=0 ( Turn off subtitles) ) but when the next avi starts automatically the vobsub subtitles are switched off (that I can understand though it's a flaw as the avi is not directly launched) and the bsplayer subtitles are suddenly turned on !?! (though I also put DefaultSub=0 on the second bsi file).

Weird, weird, weird...

If only bsiplayer could handle those multi cds subtitles well...
