I think I'll even be able to interrogate the box to find out what channel it is on before and after the script runs (which is important, because there is an error generated if I try to switch to the channel it's already on.

Hi Michael,
That's fantastic - your script works perfectly (and I was having trouble getting my head round python - for some reason, even though I had set the channel variable to that it matched the correct hex code, I kept on creating an XML string that wanted to change the channel to FA1 - I just couldn't see what was setting it!, I may have had more joy if I had modified one of my php or bash efforts as I know those a little better).
I may add the checking code later, meanwhile I really should get on with some real work :-)
Thanks again for all of your help, I'm sure the could be many others who will make use of your script.
Regards,
Dave.
