I guess I mis-read Cyclone's chart.
An ethernet cable isn't practical because it would be too long and have to make a difficult traverse, straight across a ceiling which society objects to.
(but that brings up a question: would an ethernet cable be better than a coaxial cable plugged into a tv tuner card, (if those even work with Dish)?)
Am I right then that if I wanted to record anything to the hard drive on the computer I would require a tv tuner card and be watching the program, that I cannot just load it off the dvr?
And that I could not load anything off the computer onto the dvr or access it on the tv?
