[mythtv-users] mythbackend cannnot autostart

[赵亚伟]

Hi,everyone
I have installed my mythtv well ,and it runs well.
But mythbackend cannot autostart.
Everytime I have to command, /sbin/service mythbackend start
I want it to start by itself when computer starting
When my computer is starting ,I get this error:  /usr/local/bin/mythbackend:error
while loading shared libraries:/usr/local/lib/libmythavcodec-0.18.1.so.0:cannot
restore segment prot after reloc:Permission denied.
What is wrong? And  how to solve.   Sorry,I am a newer for linux.
Yes ,I write some script in /etc/rc.d/rc.local such as /sbin/service mythbackend start
But no useful.
What should I do??
