Hey My VIP722 is only a week old but I keep getting the pop up that it tries to aquire signal. I stays at 0 but when i press the guide button the pic comes back. When the error is up on the screen I can't change the channel or anything.. I am using dp44plus and the dish with 118w. slot. Using a sig diplexer from dish. Any ideas?.. the box sure does run hot.. My D HR20 runs alot cooler that it.
