Anyone owning an MX-500 universal remote and a Sony DA4ES finding out that it's gonna be difficult to program the MX-500 to control the various DA4ES function settings? There are no pre-programmed codes on the MX-500 that will control the DA4ES, and anyone with a DA4ES remote knows that the majority of the receiver functions that can be accessed by using the Sony remote are dependant on the scroll wheel, which sends out an infrared signal only when pressed. So...I reckon that I would need to use the combination of some button and the scroll wheel on the Sony remote to move the arrow on the LCD display to whatever option I want to choose, e.g. DVD/LD; then program an MX-500 button to learn the signal that would be transmitted from the DA4ES remote upon pressing the scroll wheel to perform the actual selection, which in the above case would select the DVD/LD input on the receiver. I haven't tried this yet but will do so tonight, assuming of course that doing so is feasible and others who are in the same boat as myself have already done so successfully; if this doesn't work, hopefully someone will chime in so that I can save myself the trouble and aggravation of trying to do so.
