Over the past few days, on demand has stopped working on the TV that is closest to the router. The other two TVs in the house CAN access on demand. When I press the on demand button on the remote for the TV with the issue, it goes to DVR if I looked at the DVR listings recently or to the guide if I looked at the guide recently. I tried doing what the troubleshooting listing said and disconnected the router for 30 seconds. But I still can't access on demand on the one TV.
