Every few days I am receiving error code 004 on my 722.  I usually hit guide and then go to another channel and back to the channel that had the message and it goes away.  My setup is a DISH 1000 (110, 119, 129) and have a direct RG6 cable from the dish to the receiver.  My signal is in the 70' with clear skys.  What is causing this.
