@JohnM : Have you performed a reboot of the box? Unplug for a few seconds while it's not recording, then replug and wait about 5 minutes for the reboot to finish. It may take until the next day for the problem to be resolved. I have seen this occasionally, but usually when checking via the Home Edition App, not directly on the PVR itself.
If it stays, call Rogers and have them look into it, as well as looking into your signal strength as these devices need to have proper two-way connection. They can usually troubleshoot remotely.
