Had my HR21-700 replaced less than 2 months ago for freezing issues. Tonight there is a 14-306 error on it and the hard drive was clicking. Obviously dead. Called DTV and the tech said he was going to order me a replacement. Then he said that he had to refer my situation to a case manager and I would get a call back in 2 hours. What the heck is that? Anyone know? I've been a customer for years and never had an account issue. Has to be something else.
