I have been having issues with my PVR for a month or so now. When I watch a program that I have recorded, the PVR suddenly stops. With the statement popping ip, " Recording not available. Make sure this digital box and the PVR are connected to the network." I then have to wait 5 - 10 minutes before any recordings come back to the PVR and I can resume watching again. This is happening every 5 minutes or so and is extremely frustrating. The last time I contacted customer service for an unrelated issues I was on hold for over 3 hours. This is unacceptable. What can be done to rectify this or do I need to go to Shaw.

Before calling in, I would attempt a sequential reboot of: 1. your internet gateway, followed by 2. your PVR and then 3. any Wireless Digital Boxes.

It could be that your hard drive is failing and may need a new PVR.
