[MPlayer-users] Alsa + 5.1 surround

[jason]

dolby trailers make nice demos/tests.  I downloaded the mini_dvd.iso while 
back.

its formatted to work on a cd, but if you extract it and run it through 
mkisofs, write to dvd it works fine in standalone players.

if you want something smaller, click on the trailers link on the left nav 
bar.
