It is possible that you've more versions of ffdshow installed (i.e. a BS.Player "internal" and "external" version).
adicoto's "path" (via [Start] etc.) leads you to the "BS.Player-externally" installed version.
You should make sure to change settings in the ffdshow version as actually used by BS.Player.
In that connection please
always use (with a file loaded) the "path" as mentioned by me (as second option)
