What are pan-scan settings in Playlist/Playlist-preferences?
Maybe try (with BS.Player not active) renaming
BSPlayers settings folder.
(XP-default: C:\Documents and Settings\[YourName]\Application Data\
BSPlayer [Pro])
Upon restart of BSPlayer all your present settings will be lost and be "reset" to default. But it also eliminates all possible
unintended changes in settings effected by you.
