[mythtv-users] Nehemiah Performance

[rwk at americom.com]

Hi,

Just to see if I could tell the difference, I set my record resolution
from 480x480 to 720x480.  However, when I started watching I was
surprised to find that my 1Gh Nehemiah EPIA processor couldn't handle
it.  It sputtered every few seconds.

I ran a top from another machine and indeed observed that mythfrontend
was using 99% of the cpu.

My EPIA machine is connected to a TV through the onboard S-Video out.

As a comparison I tried the same thing on my Athlon 2200+ running a ATI
Technologies Inc Radeon VE QY video card.  I was again surprised to see
that mythfrontend was using less than 0.1% of the CPU and X was using
about 10%.  Needless to say it plays without missing a beat.

What is it about the EPIA (hardware or drivers) which makes it soooo
much slower than the Athlon system?  The difference is CPU power is not
enough to explain it.  Is it the video drivers?

And why is all the processing in mythfrontend on the EPIA box, and in X
on the Athlon?

Thanks for any and all opinions!
