[mythtv] architecture, compilation and performance

[Mark Cooper]

I came across this page recently :- http://klicman.org/altivec/ I was 
quite surprised by the difference shown by the charts comparing 
performance when compiled with -mcpu=i586 and -mcpu=i686 MMX/SSE. I 
would guess it would be even greater if -march=athlon-xp were used...
