What model HR44 is it? Is it a HR44-200,HR44-500,or HR44-700? I'm just asking to see if any possible lock-ups are just limited to that series(200,500,or 700).
Mine was a HR44-500, Whole Home DVR with two clients. Samsung 4KHDTV, all equipment plugged into APC 1500 series Backups XS UPS (Battery Backup). Wired Cat6+ Gigabit Ethernet.
Had no issues for 8 months then suddenly started locking up.
During live TV viewing, image would freeze, audio would continue for about a minute of so then go quiet. Reset button unresponsive, had to hard power cycle (unplug unit, count to 10, reboot). First once a day or so, then to several times a day. Then it finally locked up and wouldn't recover even after hard power cycle.
Left it unplugged for several hours, rebooted fine and worked for almost a week. Then started freezing up again. once a day, then several times again...
Finally got so bad I called DIRECTV, they sent a replacement unit. Didn't loose much, managed to watch or delete most DVR content before the swap.
Now have a HR44-700. Will see what happens now.
