If you constantly have power outages, address that issue at once. Low or high voltage will affect all recievers with what you're experiencing. If it's not an electrical issue, then try defragging your hard drive. Do this: Unplug the reciever at the power source. After twenty seconds, power it back up. As soon as the blue dial lights up, press the down arrow and record key on the reciever for about 40 seconds untill the record button turns on, then release the keys. let the reciever do its thing and once the blue "hello" screen pops on, type in 02468 on the remote control key pad; don't press enter. Let the reciever reboot like normal. If this doesn't fix it, replace the reciever. Oh, by the way, by defragging the hard drive, you will agian loose all your settings and recordings, but it should work correctly fom then on. Good luck!
