very much so but at the same time their are people that try this and instead they end up making it more complicated by doing it themselves instead of letting us just come out and set the cards and tuning adapters up properly. When your dealing with one or two sets of 13digit cablcard and host id numbers...lol..its easy to get dyslexic and if that happens there's a chance the cable card can be "bricked" and have to be replaced. Which then makes it worse because our allotment of cable cards are shared between multiple area contractors.
Their are things that make it difficult that are out of the customers hands and some that are. If someone is able to get it installed without us coming out..more power too ya..but for the sake of future eq, time and signal issues I would personally prefer the in-house visit
