hi there - wow - many thanks for this. this is extremely helpful. i have uploaded the code and changed the TP file to make some new buttons. i got some warning messages but loaded the code anyway. i can understand what the stepper is doing as there is a pause before the IR turns on the dvd and the page flips to the dvd page. although the projector still doesnt turn on - which leads me to think if the code is ok then either the code from the crestron database doesnt work with the projector (the projector is an xl1550u and the code is for a xl2550u). or i have got the ports set up in simpl windows. i have included two screengrabs so you can see what i mean
