Wondering what is wrong. I have a Slingbox 500 and am using Amazon Fire TV. Slingbox is at my home in Texas, now set up my Fire TV at our home in Mexico to watch US TV and control the DVR. TV works as expected, but the DVR Icon is not highlighted as a viable option in the menu and I cannot use it. I read about the IR transmitter, wonder if it is because my DVR is on the side of my TV and the IR transmitter is in front of the TV - thus perhaps the IR Transmitter cannot directly "see" the DVR? I am using AT&T U-Verse. Any ideas?
