Hello.

I'd like to ask for help with VLC performance on Fedora 7.
My CPU is  Intel Core2 Duo 6600.

In windows, 1280x720 HD stream with H.264 plays fine
and the load is split between both CPU cores.

In Fedora7 running on the same computer, VLC can't
decode and display this clip, while top indicates that the
whole VLC process runs just on one CPU core:

Cpu(s): 50.8%us,  1.5%sy,  0.0%ni, 46.8%id,  0.0%wa,  0.2%hi,  0.7%si,  0.0%st
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
10405 petr      20   0  240m  95m  26m S  104  4.7   0:13.03 wxvlc

I'm using VLC from Livna RPM as suggested on download page for Fedora 7.

Could you please suggest how to make VLC run on both CPU cores in Fedora?

Thanks, Petr
