Hello - Recently got my sling and connected it to my 722k, thanks Dish for the promotion! But, I noticed I cannot tune any Sirius audio channels from dishonline. Is that by design or am I missing something? I went with the sling to be able to watch all my Dish programming on another TV in my house (have an HTPC connected to it) and no Sirius is a disappointment...guess that's what happens when you don't want to pay the fee for another receiver... Can someone confirm this is the way it is supposed to be? Thanks.
