I have found a way to turn off the dl-500 with a pronto. Set up a device page to store the menu,down, right, and trigger button from dreamvision remote. Learn all buttons into the device as usual. You must take care in entering the down and right buttons as they are mouse driven and only need a small burst. Then create a macro using alias' to first hit the menu button. This will activate the menu. Add a .2 second delay. Then use the down and right buttons to position the cursor on the menu driven off button.(This might take a few tries depending on how much each of your recorded commands moves the cursor, I have also used default delays between ech down and right command) Add a .2 second delay then use the trigger button.(I have also found that it makes it quite easy if you run your dl-500 macro previous to running the rest of your power macro since the projector will revert to 4;3 screen when source is lost.)
