I see... I don't know about .bsi files cause I don't use them. I use bsplayer.ini files instead. This works perfectly in any version of windows!
The autorun.inf will be something like that:
OPEN=c:\program files\bsplayer\BPlay.exe
ICON=c:\program files\bsplayer\BPlay.exe
and the bsplayer.ini file must be placed into the root of cd along with the autorun.inf. If you don't know how to make one, I'll tell you: It has the same content with .bsi files. :D
