I have a AN-MR650A remote that came with my new OLED55B6P. Apparently, the "universal" feature is not compatible with my DISH
VIP 722 DVR nor with my SONY STR-DH500 receiver. In the good old days, I would have entered a code to operate these devices with a true universal remote. Is there a way to do this with the AN-MR650A? LG customer service is unresponsive.
