BSPlayer can't play video when screen is rotated

[jpnn80]

BSPlayer Free 2.00 build 937 always gives alternatively the 2 following and identical error messages when I try to play the same xvid avi file or others in any order, after that I rotated my pivot monitor to 90° left in portrait mode with the option from ATI display driver, whereas in normal landscape display, BSPlayer could play the files perfectly with filters like xvid decoder or ffdshow, and other players like VLC or MPC could play the files too even when the screen is rotated:
