Hi,

Last night I setup an IR blaster on my myth box (knoppmyth R5A16) using this guide, http://mysettopbox.tv/phpBB2/viewtopic.php?t=4462

I got to the point of making a channel_change.sh script which works flawlessly on the command line. But when I put the change command into the correct box in myth-setup (and reboot to make sure it's picked up by mythbackend) It doesn't change the channels. The script has its permissions opened right up and is executable

This is the output from /var/log/mythtv/mythbackend.log It certainly looks like it's trying to run the program when I change the channel

Starting up as the master server.

this is the output from a "tail /var/log/syslog -f &" You see that I run the change command first in a shell, then the last 20 lines are changing channel in myth, It's not calling lirc_serial at all

Can anyone please suggest somewhere else to look to see what Myth is trying to run or where errors I'm missing might be printed?

Thanks

I've had an answer from the mythtv users list.

I need to put the channel number in the channel number box on the first page of the channel setup AND in the freq ID on the seccond page.
