Have something strange going on at a customer install. I have an MX-850 with a MRF-250 radio base station. Programmed the MX-800 and learned the codes from the new Denon remote. Volume control is very intermittent. Works sometimes, other times nothing. I tried learning with the tap-tap-tap method. I got better results. Everything seems to work fine with just IR when in front of the gear. As soon as I connect up the MRF-250, the volume control and others don't work. Or, work less than half of the time.
Here is the interesting part. I set the 250 address to "0" to look for RF interference. The activity light is on solid. I shut off components one-by-one. Old cable box, no problem. But, when I power doen the Denon piece, the activity light goes out and stops flashing.
Anyone having or finding the same issues??

Thanks,

Ed
