It works from the command line, but not inside Myth?  Are you running it 
from the command line as the same user that's running Myth or as root?

If it works for root, but not for other users, it's possible your users 
do not have access to accurate enough timing information to make the IR 
signal work properly.  Try executing:

echo 1024 > /proc/sys/dev/rtc/max-user-freq

as root and then testing the channel change as a non-root user.

HTH.
