I'm a DirecTV customer considering switching over to Dish network because they have a lot of HD channels that Direct does not currently have. When I go to dishnetwork.com or dishtv.com to build an order and select programming, receivers, etc., neither site offers the 922 any longer for and HD DVR. They both only offer the 722 with Sling adapter. I can't find any posts or threads that say the 922 is being discontinued so am wondering why I can no longer select it. Thanks in advance for any info on this.
