My PVR 630 is about 8 months old. From the beginning it would randomly reboot infrequently, once a month or less, otherwise it worked fine.
Lately it has started rebooting randomly at intervals of 15 minutes to 2 hours. It will lock up as well and not respond to the remote. Unplugging to reset will get it started again but it will shutdown and reboot again quite soon, like 15 to 60 minutes later.
It responds very slowly to the remote. The remote has new batteries. Switching channels, will cause it to reboot. When playing a PVR recording the playback is jerky and constantly stopping and starting. Exiting from the guide is very slow, like more than a minute and sometimes exiting from the guide causes a reboot.
Any suggestions for a fix other than replacing the unit.
