[mythtv-users] CPU performance for Atom on BE/FE

[Josu Lazkano]

Hello again, I have some playback problem on a Nvidia ION based BE/FE,
I am checking the VDPAU. But I read this post:

http://www.mythtv.org/wiki/VDPAU#CPU_Frequency_Scaling
https://bbs.archlinux.org/viewtopic.php?id=64564

So I want to know if I need and extra configuration on my CPU to
better performance. This is my CPU:

Is preferable to disable the CPU stepping?

I will appreciate your help. Maybe this is the cause for the playback.

Kind regards.
