True that the national nets have open positions for the providers, cable sat etc, to insert their own ads or promos, for the sat providers, like Dish or DirecTV to sell and insert ads on a local level, or regionally specific level although I would think technically possible would be fiscally not prudent, or at least technically unfeasible because it would take extra bandwidth which they are crying they don't have. The OP is indicating a local or regional ad ran on a national network on Dish. I've yet to see that sort of thing happen. Closest would be on an RSN which is part national programming but done locally and would be easy to insert local ads. Cable of course does it all the time. Easy for them, since local or regional head ends insert the local stuff. Satellite would have to use separate spot beams for the local ads and then re map your receiver to switch to the ad transponder when needed and then switch you back to the regular feed when done. It would probably be sloppy at best in clean transitions, and then the extra bandwidth comes into play. He does indicate that his DVR recorded a national ad in that same position. Maybe they are doing the local spot beam thing but it only maps the receiver to show the local ad but not interrupt the feed to the recording?
