[MPlayer-users] Altivec IDCT & audio un-sync problem (ENGLISH)

[Zsolt Kiraly]

Hi Robert,

Actually all dvds play unsynced or slower than normal in my PowerBook. 
These dvds play normally on VideoLan on the same laptop, and also with 
mplayer on an Athlon under RedHat 7.3.

So I suspect that there is some kind of bottleneck on my laptop. I am 
using SDL for video output (sdl: Quartz). Anyone know if it would be 
faster using something else on the Mac ?

I do have xfree86 installed, and the configure script did pick up the 
x11, xv and openl support, but none of those seem to work.
