[mythtv] h.264 multithreading

[Riz]

I'm using "mplayer 8940_20071120195900.mpg -lavdopts threads=2"

with that set, I get even usage of both cores

Cpu0  : 67.4%us,  0.7%sy,  0.0%ni, 29.3%id,  2.6%wa,  0.0%hi,  0.0%si,  0.0%st
Cpu1  : 64.4%us,  0.6%sy,  0.0%ni, 34.9%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

without the threads=2, playback is the same as with mythtv i.e. one
core hitting 100%

The stream is from BBC's HD channel on DVB-S.
