I have Dish 721 PVR that I am having alot of problems with. The guide screwed up a couple of days ago and it is still not right. The PVR will no longer record, I cannot pause or rewind and cannot set up timers. All of my PVR'd shows are completely gone as well as all of my event timers. Does anyone have any suggestions? I have tried all the usual reboot, kill the power, switch check nothing seems to work. We had all of it back and working fone about 8 hours ago but has been down since. When the guide is working I can change chanells and view TV as normal. I know this is a long winded post but I do not know what to do. Please help.
