The easiest way to make it reappear is to delete BSplayer preferences file (
C:\Program Files\Webteh\BSplayer\BSplayer.xml or
C:\Documents and Settings\USER_NAME\Application Data\BSplayer\BSplayer.xml or if you are using Vista
C:\Users\USER_NAME\AppData\Roaming\BSplayer\BSplay er.xml)
As for the BSplayer settings file, it's
BSplayer.xml, located at one of the locations I listed you here above
Here I uploaded a tool to retrieve BSplayer's controls window, I can't recall if it also reset Video window position, but I doubt it..
