HDPVR reset its OS - deleting saved shows and schedules
Now, I wasn't all that thrilled with the "upgraded" OS when it came out a couple of months ago, it was very laggy and slow. However, rebooting the PVR helped and I've gotten used to it.
Imagine my surprise, when I just realized that my PVR isn't recording a show, and it's supposed to. I turn my TV on - the PVR's OS has reset to the old one, deleting all of my saved shows and scheduled recordings.
