Thanks for all your help John. Do you have a table that lists the protocol types to generate the necessary hex codes for the remote? (Ie. how to know which .irp file to use).

I think you're right John. I found another power toggle at hex92 but no discrete on or discrete off. For DVD players and other devices where there is no discrete on or off can you advise how I can ensure the device is ON or OFF for my macros?

Thanks again for all your help.

Paul.
