The 722 that I just received from DISH constantly reboots when I am recording a program on the DVR. During a hour program, the receiver will go power off, reboot and then go thru tests 1-5, then start recording again all without customer input. This happens 3 or 4 times during all recordings but only during DVR recording. Not while watching programing. DISH says it is caused by the signal being interrupted by weather problems. Can this be true? I don't understand how the weather can effect the DVR recording but not the normal reception. HELP!!
