I've been given a RePlayTV..a 5000 series, and I don't know whether it has a lifetime service or not. Does anyone know how I would check this?
Replay has been sold a few different times since 2005. It is currently owned by DTM Holdings (Denon, Marantz, McIntosh). http://www.digitalnetworksna.com/replaytv/
I'm not sure if you're going to get any useful information out of them.
