I've had my Pro-HD for years, and it usually gives me no problems. However, recently Verizon Fios changed all the boxes in my house to Quantum, (the new boxes are by some company called Arris). After rewiring the new cable box and Slingbox, I'm getting an error on my Slingplayer saying 'No Video Detected.' The audio is coming in fine, and I can control my TV at home just fine as well, just the video is not working. I'm certain that the wires are in correctly, could it be that the outdated Pro-HD is not compatible with the new Verizon cable boxes? Maybe the Quantum technology does not work with the Pro-HD?
