Intervideo ac3/Bsplayer

Hi Folks,

I've got Bsplayer 805 and Intervideo WinDVD 5 Platinum.
So I've got the Intervideo Audio Decoder installt.
If I want to play an AC3 Stream in BSPlayer all works fine,
but when I run a Video with an AC3 Stream, nothing will
be played.
It's very strange.
I tried uninstalling both, first install WinDVD then Bsplayer
and versus, but nothing worked.
maybe you got an Idea where the Problem is.

Ciao, Band

BTW: The Preferences on the Intervideo Audio Decoder
Page don't save on Videos but on Audio-only AC3 Files.
Don't know if this two Problems are connected.
