In my home office I have a single coaxial cable coming directly out of the wall. I put a splitter on the cable so that my laptop and my TV both get cable service. I have a Magnavox DVR hooked up to my TV so that I can record a program that airs at the same time I’m watching a different channel or airs at a time that I’m unable to watch live. Cox has gone “all digital” in my area. How do I configure the mini box so that I can record to my DVR? Can I program a show to record on the timer?
