I´m a steady graboid User but when I Stream XVID movies I get no Voice, just music & sound effects. Why? I use soundblaster Audigy 2, ATI Radeon 9000 video card. I´ve installed media player classic and AC3-filter but nothing works, the problem is only with XVID. Is there a magic setting combination I can Use, or a super program I can download? I use Dolby pro logic surround on my analog surround system.
