Honestly its because of the new Sling Adapter of why its being done. They expected the Sling Adapter to work with the 622, but in testing found that when the receiver tries running background maintence (such as updating guide, checking timers, checking internet connectivity, etc) that the Sling would not function without a lot of stuttering and dropouts.
Thanks again for this extra detail on Dish's usually inscrutable internal machinations. I have two questions.
What the h%%% are they doing? Scanning ports? All these receivers should have a prioritized interrupt system in the O/S so that video streams take priority over background stuff that can wait. I forgot to say, "Argh." Argh!
OK, 2nd question brought on by the nice detail of the quoted message. Any hope for Sling Adapter support in other VIP receivers, such as the 612 or non-DVRs?
