I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/message/10363#10363
Come back if it that doesn't help either. BTW, The internal IR blaster on the M2 is very powerful and should operate anything within a few feet.
I just purchased a M2. Connecting through a Cox mini-box model HD-uDTAc. From my searches, I believe this to be an Evolution brand. Setup with Iphone, video stream works but remote does not. Tried all codes 1 through 9 under "other"
Does anyone know if there is another choice for the remote codes? And a stupid question, how does it change channels if not using IR extender? Does the box need to be facing the cable box?
(Also using HDMI converter from Frontier) Thanks for any tips and info.
