If you are using cpufreq I've found that can hurt perf with ffmpeg/mplayer.

The default threshold is too high, but even lowering it doesn't always 
seem to help.

Whenever I play/encode I've taken to just forcing it to perf -

echo performance >  /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

repeat for cpu1 cpu2 etc

to turn back down
