I had no trouble connecting to my old Motorola set top box. Now I have an Arris set top box (Quantum service). The new set up of the M1 seems to go well using the Slingplayer Desktop. Video is supposedly found but all I see on my MacBook is a black screen with audio. I have read so many articles and tried reconfiguring it multiple times and I have no idea how to make this work. I'm not the least bit techy and never needed to be before. Please help!!!
