My ability to use the remote control stopped working yesterday while i was watching on my desktop. I had already been watching for a few hours with no problems. I tried to reset, but no luck. Also tried using the app on my ipad but it didnt work there either.I tried moving the cable box closer to the sling box and i could only change the channels if i held the cable box up face to face with the slingbox.....so i ended up pulling out the ir transmitter that came with the slingbox and that works. but it was working fine without it before yesterday.what gives?
