[MPlayer-users] hwac3 option speed up video

[Marcin 'Aznar' Czachurski]

Hello!

I have problem with mplayer in Windows. I have a few movies with AC3
sound. When I play them in mplayer, without hwac3 option, everything
is OK (but on my audio amplifier I have only two channels). However
when I add this option to the config file, video in this movies is
much more faster (two or three times then normally). Sound is perfect
(I have six channels in passthrough mode). Do you use hwac3 option in
mplayer in windows? I have to change something else in config file ?


Software:
  MPlayer-athlon-svn-29355.7z (from
http://oss.netfarm.it/mplayer-win32.php site).
  Windows XP
Hardware:
  Sound Blaster Audigy
  AMD Athlon 64 X2

My mplayer config file:

quiet=yes
nooverlapsub=yes
osdlevel=1
ffactor=1
subcp=cp1250
subfont-text-scale=3
fs=1
alang=en
afm=hwac3
cache=512000
