Advertisements Set up Roamio Pro last night. Moved cable card from XL4 to Roamio. Called activation number - all channels activated automatically, except for HBO which required a call. HBO came on but is breaking up badly. HBO was working fine on the XL4 with the same cable card, same connection. HBO is still working fine on the other XL4 that is still connected in another room. All other channels on the Roamio including other premiums like Showtime are working fine. Signal strength is 90-95 on all channels including HBO. I tried changing the Roamio Tivo setup to only use 720p, but that made no difference. Signal runs to a Sony ES-series receiver (about 5 years old) and Sony flat-screen HX929. I will call Verizon FIOS and ask them to push the HBO pairing again. Any other ideas?
