At risk of pointing out the obvious, I was expecting you to test the 
same output device in mplayer as you were using in myth...

Can you go back, check your myth config, work out exactly which audio 
output device you are using (/dev/dsp or ALSA:blah), then flex the same 
thing in mplayer.  If there is any hardware AC3 decoding going on, then 
obviously disable that or else you won't be testing the same thing in 
myth as you do in mplayer!!!

Perhaps, but this might mainly be because the cpu load is higher.  What 
is your CPU load by the way?

Please debug this a little for yourself and supply all the interesting 
info here
