Bought a new XL4 and haven't been able to get RedZone channels (SD & HD) working on it. My old Series 3 cablecards receive RedZone and I have already tried swapping them into the XL4 without success. Verizon sent me a new cablecard and same situation. I do receive HBO on that card without problems once I have them pair the card. But I can't seem to get RedZone working on it. Doesn't make sense that it would be a hardware problem because it receives HBO. Fios support is awful like all other cable companies. Very frustrating hold times and general stupidity in the people I am talking to. Anybody have any ideas of why this is happening? I had the HBO problems a few weeks ago on the S3, but was fixed once they manually input the Data ID I gave them.
