When in the heck are they going to fix the ****ing freezing problems? I'm fed up and want them to fix the damn problems with the HR21-700 freezing constantly. No buttons work on DVR or remote yet picture and sound work. I'm sick of this. I had the CE build from Feb 1 and no problems, why then was I downgraded! DTV will not refund me any $. They don't seem to want to do anything to help. I really need to know what I can do. My parents won't cancel the service. So what in the world can we do?
