I came home tonight to find my 921 with a Frozen picture on the screen. The unit was not responding to the remove so I went to the front of the 921 and held the power button until it rebooted. Next the Dish HDTV logo popped on the screen and stayed there. After a few mninutes later there was a DishLinux Screen telling me that the remirroring process failed, and system failure. After that another screen popped up saying the following YOU DISK HAS FAILED You Still Have Some Service Available I have attached a photo of this screen (which BTW was Copyrighted 2001 which I found interesting) Software Version is L142 Boot Version 120B Flash F051 Another 921 is being sent to me, I hope it makes it here BEFORE the SuperBowl.
