Thanks for that! I seem to have most things covered, apart from.....

Is there a "discrete" code for switching to a particular function (e.g. to Video 2). The standard remote that came with the system uses a "function" button to scroll through the four options available. I have found that if you press the Play key, the DVD Function is used. So currently, to use Video 2, I have a macro that presses play, and then scrolls forward twice to the Video 2. It works (sometimes - gets a bit confused if the DVD player is on Standby) but is a bit messy.

Thanks again - maybe you can help.
