[mythtv-users] mythpreviewgen using 100% cpu

Hello,

I updated to 0.25 and it still continue getting stops on playback on
my combined frontend/backend. What is the function of the
mythpreviewgen?

I try with the wrapper script with nice to reduce the CPU load. But it
doesn't work: http://dl.dropbox.com/u/1541853/mythpreviewgen.png

This is the script:

# cat /usr/bin/mythpreviewgen
#!/bin/bash

# Script to reduce CPU impact of preview generation at the end of a recording.
# mv /usr/bin/mythpreviewgen to /usr/bin/mythpreviewgen.real
# copy this script to /usr/bin/mythpreviewgen
# chmod 755 /usr/bin/mythpreviewgen

nice -n 19 mythpreviewgen.real $@

My combined backend is Zotac Ion ITX-G with Atom CPU, I know that it
is not a powerful machine.

Anyone with this situation? Is possible to reduce the load of the
mythpreviewgen?

Regards.
