I got the problem that my settings are NOT REMEMBERED, all incervideo settings switch reset back, im on Audigy 2 Gamer Zs, and Logitech Z-5300e speakers. this means the sound plays just like stereo.

my specs:

Windows XP SP-2 all up to date.
1.5 GB ram DDR 333Mhz ( Pc 2700 )
AMD Athlon XP 2800+ barton core at retail speed.

Logitech Z-5300e on 5.1 mode, options on console are set to 5.1
BS player 1.22 Build 817, 24 Feb 2005.

Bs player as been set as "Ac3" filter as default filter for AC3 sound, also main sound device was set to "Creative Labs Audigy"
also vocals sound VERY WEAK.

note, most of the time im testing it with my movie LOTR, The Two Towers,
