With any HD FTA receiver you can only get Bev HD channels. To get Dishnet HD channels , you MUST have an add on 8psk module/module ($169-$199) installed into your receiver. Ebay sells them, along with some other sites.
BTW..the Sonicview 8000 is the best HD receiver on the market now and at any time but still only gets Bev HD, without the 8psk module, needed to get DN HD channels.
