to expand upon this (this is what im told from my office, not sure whether its true or not) when you put up a ka/ku dish and not the ka/ku3 the receivers will use the 119 sat for guide data because it has the least amount of traffic on it nation wide currently. If you have no los for that bird and install the dish anyway you will start to see alot of 920 errors. and that basically means that the guide wont update anymore. its like the first 24 hours of setup, where you have title not avail, unannounced, etc. well think of having that on random channels all the time, and if the receiver cant tell whats on the channel, when you tune to that channel it will show a 920 error. think about what this would do to dvrs (yikes) so if your missing the 119 on a high deff install, you need to use a ka/ku3 dish (3lnb) that will force guide updates to the 101, problem is it will also prevent you from ever getting locals, and if the 119 carries locals in that market, the techs prob dont have access to that lnb.
edit, this is just what im told, but i have rolled on service calls out in jersey where locals are from nyc on the 101 and corrected 920 errors by changing the lnb (the case was the cust did not have los for 119)
To my knowledge the 110 carries only spanish programming, and the 119 carries only locals in select markets, legacy hd, and guide data.
