The only other thing I'd wonder is - is there a physical fault in the IRblaster, but the fact that the script works from the command line suggests not.

so I'm running this on CENTOS and I see something in the startup script 
about it not running as mythtv because of some missing groups.  Thats 
most likely the reason I'm root.  Given that this box has a single 
purpose and its not internet accessable I'm not overly worried about it.

so I have edited the script to do as you mentioned.  I am showing UID 
and EUID for 0 for both.  This is the only myth box I have.   i did a 
yum reinstall lirc  and it didn't seem to make a difference. Appreciate 
the help in solving this as do my kids who are anxious for some new 
cartoons to watch.

:)

Appreciate everyones support on figuring this out...
