Need help with bspfilters.dat

I am making an autorun with BSPLAYER and now I have two problems with the bspfilters.dat! When I have the AC3 filter loaded no mp3 sound is playing and when I change the file, that the ac3 filter only loads when there is an ac3 stream in the movie, ac3 dont plays!
That is my actual bspfilters.dat:

[BSPlayer filter def file]
AddFilter divxdec.ax,{78766964-0000-0010-8000-00AA00389B71},DivX 5 Decoder

MPEG1={4A2286E0-7BEF-11CE-9BD9-0000E202599C},MPEG1 Audio Decoder

this file I am using only for divx movies with mp3 sound! It functions very well, but today I had a problem with it! On another pc with winxp and no codecs installed, the movie didn't play!

And that file I am using for movies with ac3 sound!
