While I had read in many forums about the many problems people were having with the 921's, I was also taken in by all the hype and ads that talked about this great system and finally caved in a bought one. Needless to say I hoped that the few misfortunes that happened to other people were isolated incidence and I would be one of the lucky ones. Well, I regret to say that I was not. The technician came today to install the machine and it booted up fine. Picture looked great and everything went very smooth. The tech then proceeded with the "software upgrades" and half an hour later, the whole machine went dead and started rebooting itself endlessly. He proceeded to call Dish Network Tech Support and asked for "advanced Tech", they unfortunately were just as clueless and after half an hour of trying various unpluggins, resets and so forth, proceeded to tell us that our case would be transferred to the "921 Beta team" and they would call us back in.... "48 to to 72 hours"!!!! That is 2 to 4 days!! You got to be kidding me! That is the service we get for purchasing their top of the line DVR? Needless to say I am very disappointed in Dish Network for not having the proper support which results in us having to wait up to 4 days and secondly because I feel stupid not having listened to all the many complaints about this system. Obviously they have a very serious quality problem and Dish Network should be ashamed of themselves to even consider continuing selling these units. What is even more concerning is that once they get this unit fixed or replaced I will have the constant worry that I own this unit and when it dies in 1 to 2 years I will be out the $550. I felt the need to share this story as I feel that the more people talk about their disatisfaction that maybe these companies will start paying more attention to customer service and quality manufacturing. I will close with an even more disappointing discovery, these units proudly say "made in the USA". Shame on you! no wonder we are getting our butts kicked in the tech manufacturing field! I cannot recommend this unit, stay away from it!
