Well, one of the fans is going out on my 622...it has a high pitched whine and their is a distinct vibration of the unit.  This will be receiver #5 since march, almost once a month...not a good track record.  If this one fails, I'm dropping dish...the whole experience from the start has been a nightmare.  It took 6 weeks to get the first unit but they made sure to take my money the same day of the order, another 2 to get it installed, replaced units due to HD failures, OTA tuner, constant reboots, taking 4 weeks to get a 1000+ installed, billing errors...you name it.  Plus the problem with the last two updates...DISH YOU GET ONE MORE CHANCE!!!
