The most important file for your purpose is BSplayer.xml !
Like I wrote previously: its whereabouts depend on what you selected at installation of BS.Player.
It may be present in the folder
C:\Documents and Settings\[YourName]\Application Data\BSplayer [Pro]\
(under WinXP)
or - if you're a user of Vista or Win7 - in
C:\Users\[YourName]\AppData\Roaming\BSplayer [Pro]\
or in BS.Player's installation folder
(default C:\Program Files\Webteh\BSPlayer [Pro]\)
What is your OS?
P.S.: There are more "versions" (in fact "builds") of BS.Player 235. The most recent build to-day is 986. So it is better to always mention full version indication (235.986).
