2 Hoppers, one with 237 and one with 234, both doing the same thing. Just picked up HBO for the half off for 6 months. When pulling up ON DEMAND, picking CHANNELS, HBO, when scrolling through the list when you get half way through the H''s it comes up NETWORK CONNECTION FAILURE. I tried the Starz On Demand list which is even longer and it works with no problem. Anyone else run in to this yet?
