If you want to be sure, ask Rogers when you sign up. Note that if these haven't been used in a while, you may have oxidation on the ports, or the Hard Drives on the PVRs might not work properly, or they may not boot easily, etc. Do not expect a smooth startup on old equipment.
That sounds about right. I just noticed that whole home pvr is no longer an option on new accounts. That might just be a deal breaker. It'll be hard for my wife to live without something she's had for 5 + years.
