I don't understand the question. when i had Dish they gave you locals for free. so why drop them in the first place? second i don't think the
DVR has an A/V in to facilitate a converter box, only A/V out. seems if they did have A/V inputs the
DVR-capability would be exploited without benefit to Dish, who truly owns the receivers and rents them to the user. so i doubt they'd let you record from any input, much less a converter box. otherwise you'd have people recording their PC data to it and using it with their TV and many other exploits. i think it would also violate Dish Network terms, customer or not.
