Embedded Sling [DaVinci]:
Didn't work well for 922 - fact.
813 doesn't have the Sling chip - fact.
No more 922 deploying - fact.
The problem is with your conclusion:
"After fiasco with embedded Sling (model 922) ...
You concluded that embedded Sling was "a complete and ignominious failure" (which is the meaning of the word fiasco). We disagree.
Embedded Sling is now working on 922s. There is no reason to assume that the DaVinci chip would not work in the next receiver DISH designed, especially one based on the 922. DISH worked out the bugs with embedded Sling on the 922.
DISH also had problems with Sling on the lesser receivers. It seems odd to focus on problems one receiver had with Sling without acknowledging other receivers also had problems. I see the problems as Sling related, not embedded Sling related. There was nothing more wrong with embedded Sling than USB Sling.
It was a business decision not to spend the money needed to put embedded Sling in the 813. Sling is easily available via the USB adapter ... just plug in and go. Many customers upgrading to Hoppers already have these USB devices - just plug in and go at no extra cost.
It was also a business decision to stop deploying the 922 ... and quite frankly, after seeing the whole home Hopper in action I don't see why anyone would choose a 922 over a 813. Perhaps if someone never intended to share their content a 922 would be better, but with the third satellite tuner I'd still choose a Hopper.
So, in summary, is Sling itself "a complete and ignominious failure"? No. Sling is still offered. Is the 922 receiver "a complete and ignominious failure"? Perhaps, but DISH basing the 813 off of the 922 shows that there was some good in the design. So any failure would be far from "complete and ignominious." Does embedding Sling in a 922 somehow combine to create "a complete and ignominious failure"? I think not.
