I have never really done anything to maintain my DirecTV channel lists... When I pull up the guide, it is ugly... all the PPV, sports channels, premium channels, adult channels... All of them are visible, even though they are not all available... I started to do some pruning using a custom list..here was my process 1. Filter out all SD locals where a HD local exists 2. Filter out all PPV channels 3. Filter out all Premium Channels (I don't subscribe to any of them) 4. Filter out all private network channels (do these stay consistent?) 5. Filter out all "XM for Business" channels (channels 95xx) 6. Filter out all Game channels (channels 99xx) 7. Filter out all obvious non-interest channels (e.g., non-english programming, etc..) What I am left with is still a lot of channels... I still have not pruned the informercials, the direcTV preview channels, etc... Some questions/issues: * How stable are the channels outside of the mainstream * What about seasonal channels, for instance, the US Open have about a half dozen channels broadcasting tennis... How does DirecTV inform us of these sorts of "special" channel assignments? * I am pretty confident of the stability of the 2-400 channels... Not so comfortable with the 500s outside of the typical premiums, and then the 600s and 700s seem a bit of a mystery for me on stability... How do you all manage your channel lists?
