[MPlayer-users] AC3 passthrough

[Marcus Willander]

I know that the manual says that it's not possible to use hardware AC3 
passthrough with a soundblaster live + OSS. I'am using OSS and i'am able to 
get the sound perfectly through the card but the video is very very sluggy. I 
see about 1 frame/10 seconds or so. CPU usage is around 5 % and normaly it's 
about 30 - 40 %. 

Is there any setting i can tweak to fix this?
