You used to be able to see the 922's menus and were able to navigate them early on using a pop-up remote via Dish Remote Access website or the Sling Mobile apps. Over time they've limited how many remote functions you had access too.
Mike, I think you're really misrepresenting what happened to these boxes. Just because you had issues with the 721, like you did with the 922, doesn't mean that everyone did as other people have mentioned. Like navychop said, the 721/921 was pulled in 2008 because of the Tivo lawsuit. Before that DISH had been rolling out updates for the 721 box for FIVE years. The 921 was supported with software updates for four years. Those don't sound like an "abandoned" products to me. If the 922 is still supported with firmware updates for the same five years from release, I think that sounds about right. The way you spin it- It makes it sound like these boxes were pulled from shelves after a year on a market.
If anything, this is evidence to support my theory that the 922 is the first box that runs DISH's newest version of receiver software that will be taking forward. Especially since we know that the 813 is going to be based on that same software. So I guess I'm saying that the 721/921 are kinda like the 922 in that the software that those two receivers were running became the basis for the other VIP series receivers that came after it.
As for the 721/921 PVRS, they are now defunct yes to the Tivo lawsuit. But my point was the whole software used , the Home menu , the guides etc were also Abandoned. They are no longer used. IF you had a great experience with them , good for you. IN my personal opinion and experience it was not a great experience when I got up in the morning to a failed hard drive on my little boys 721 and NO RECORDINGS possible. A 2 - 3 year old with out his Sponge Bob is not a happy boy.
As for the 922 interface, I imagine they will be using the software , menus, channel logos etc with the 813 Xip series of whole house dvr. But the 922 with Built in Sling , is not going to be produced any longer in ANY new line of receivers. DISH discovered they could do it cheaper and do Sling with existing class of Vip series of dvrs and it worked BETTER than the Built in 922. So I say again, in my opinion the 922 As a stand alone ,built in sling receiver , will not be reproduced in any later models , so it will too be Abandoned as a class of receiver. It has taken too many years to get it to market , and it still suffers from a lack of some basic features the older Vip series has . Blockbuster is one, soon to be rectified via software update this month ,supposedly. The manual timers and DISH pass timers can only be created online, not through the receiver. The whole concept of TV2 in HD using the sling extender, looks like it too will be Abandoned. DISH has once again moved on to the latest and greatest "cutting edge " high Tech Receiver , the 813 whole house dvr.
The 813 Xip series of dvr too will suffer from bugs and glitches and software problems , especially if they are based on the 922 series of receivers, minus the built in sling. So although you have had wonderful experiences with the 721/921pvr and the 922 dvrs, doesn't mean that everyone else has. Obviously since they are no longer selling the 721/921 or any other model after that with that software, menus ,guides ,etc and because the 922 dvr is now being issued minus the $200.00 upgrade fee, means to me that it too is being Abandoned for newer class of receivers: 813 XIP whole house dvr. This is a continuing cycle with DISH. They try to operate like Apple ,offering a newer class of receiver every year or two with the latest do dads that they think subs will want. Except with DISH , they can't ever get a receiver to market without the glitches , bugs , and general problems. Evidence by the long trail of failed abandoned class of older receivers like the Web tv/dishplayer 7100/7200 models, the 721/921 pvrs, the 942 dvr with name based recording and I truly loved that box. The 922 will now join the long list of now defunct receivers that are no longer being marketed and sold as cutting edge. Yes it will continue to get software updates as long as their isn't any lawsuits or problems like the older receivers I mentioned. But I don't see them marketing the 922 any longer as the best "flagship dvr". When the 813 comes out , that is all you will hear about with great promises of things it will do , and it too will fall short in it's delivery.
I guess after 15 years with DISH , you become jaded a bit. I am tired of being promised all these features that never come true. It is like DISH is a politician who never delivers on what it promises , except that they are the lesser of the two evils : Directv and Cable. So I continue to stay with them and pay my three accounts monthly. But it doesn't mean I have to shake my pom poms any longer. DISH promised too much with the 922 and didn't deliver and now they put the final nail in the coffin and it looks like no sling extender for tv 2 in hd either. The whole reason I wanted the 922 was so I could do HD on tv 2 in my home, NOT ON THE INTERNET.
