AC3Filter

I use the ac3filter from ac3filter.sf.net. When I open a avi with a ac3 track in it bsplayer use both cyberlink audio codec and the ac3filter codec from ac3filter.sf.net. How do I only use the ac3filter from ac3filter.sf.net.

There is an updated version available. I use this codec with every backup of my DVDs .. superb sound. I wish BSplayer included support for selecting this filter.
