I recently purchased an Amazon Fire Stick, with the hopes to use my old slingbox and the Fire Stick together. Turns out this older model is not supported. I am therefore looking at either the M1 or M2 to get this working together. I am trying to find the differences between the M1 and M2. It appears the hardware is the same and therefore should be able to use either box and the fire stick together. Please advise if this is correct, or am I missing or not understanding something is the small print.
