Gee, thanks! That's a lot of information that I really wanted. I even e-mailed this link to the Cox support people locally so they could learn something too.
Well, I called Cox cable DVR support this afternoon and they agree that taking the DVR box "out of state" would not work. Apparently the firmware that controls playback of recorded files does depend on the Cox cable signal for verification. He said I could take it next door, or across town, and then hook it to a Cox cable, and that would allow me to share the recordings. However, if I went where there was no compatible Cox signal, even playback would fail.
I pointed out that a lot of people are going to be very disappointed when the next hurricane hits, their Cox cable goes out for a few days, and they can't even playback programs they originally recorded on their DVR.
Sounds like there was more "political" engineering involved with the design of this box, and its firmware, than this old engineer can really appreciate. I design software and firmware for a living, and I hope I never have to add such a "political" feature to my company's products.
