Dish network airs the same PSAs on their network and it adds so much confusion to any customer of theirs. i was a Dish customer when they started airing it and i called their tech support to inquire and they told me (incorrectly) that if i'm hearing the ads i need to upgrade to DishHD but i later found out they were trying to scam me into their
HD service since i still had one of the older DishPro systems and they even tried to convince me that they'd stop allowing any DishPro receiver to work post-transition, but after phoning other tech reps i found that to be quite false.
The truth is your dishnet satellite receiver
is the converter. it's already doing the job of one, taking a digital satellite signal and converting it to a format compatible with your TV, be it analog or digital.
