Got a technical question for all you CATV folks. The cable system I am on comes into my house on the same line as my phone. The optional DVR system that the provider supplies is rather expensive and very limited in what it can do, so I bought a Magnavox DVR that does all I want it to do. The model number is MDR867H. Here's my problem. The input to the DVR has to come from a coax cable, not the phone line. Is there any sort of adapter that can take the signal from the phone line and convert it to something that the DVR can use? What I have in mind doing is running a parallel system with the provided cable signal going into one input on the TV and the aftermarket DVR going to another input on the TV. That part seems fairly straightforward, but splitting the signal seems problematic. If there is no way I can split the signal, is there an aftermarket DVR that will do what I need?
