Add me to the list of people experiencing constant freezes and lockups on my DVR and other STBs. This often (but not exclusively) involves NBC HD channels (including MSNBC and NBCSN). Sometimes switching channels brings the picture back. More often it requires a reboot. Several times I've lost DVR recordings (I get dumped back to live TV). Rebooting the DVR usually removes the recording in question from the list. I've checked connections - they're fine. This seems to be a software problem and I'm wondering when a fix will be provided. Reliability doesn't seem acceptable given the price I'm paying for the service. I never thought I'd say this, but I'm beginning to think about switching back to Comcast. Please convince me this isn't necessary. Thanks in advance.
