Start at specified chapter

Hi all,
its possible to make Bsplay start at specified chapter (via command line) ?
I tried with -stime="begin of chapter" but apparently this work only with

bplay title.avi -stime=x

and dont work when trying to load an ini file (bplay title.ini -stime=x) or with bsi files ( "bplay title.bsi -stime=x" nor "title.bsi -stime=x")

Im doing something wrong? or there is another way ?

Thanks
Bye
JT
