Black screen on Multi-CD, played from BSI files

[MtK]

Hi,
I have a multi-CD movie played through the TV-Out.
whenever the first CD ends, it starts the second CD, but the screen goes black.
I can hear the sound, but see no picture nor subtitles...
I tried showing the movie without the BSI files, & it works just fine...
I tried changing the BSI, but no good...

Important Info:
It happens only in full-screen.
It happens only with BSPlayer. (checked WMP)
On my LG monitor it works just fine.
I have tried playing with the overlay options.
I have DirectX 9.0b
Ati Readon 9000 PRO, Catalyst 4.7

Any Ideas?
