Just switched from DTV to FIOS 3 days ago and am already buyers remorse. The DVR randomly shuts down and turns back every few seconds, but only after it prompts us to turn on FIOS or press the MENU button. I've called technical support 3 times: hung up once after being on hold for 20 minutes and was hung up on twice by the Verizon system. So far, the online technical service has been anything but helpful. About to pull my hair out! Any similar problems out there or suggestions for repair?
