my son used to work for dish and he has no idea...previous receiver had to be replaced because it did the same thing and then the hard drive died. this is a new receiver (less than 6 months old) almost every day, it will freeze up at the same time (2:02am and pm, 6:02 am and pm, 10:02 am and pm) wires and cables are all intact, unit not overheated, will do it with or without the external hard drive hooked on. it is getting real annoying especially if dvr'ing an event or a show you really waited to watch. HELP!!!
