:Also with a networked DVR service, you are subject to the same problems people have with VOD - and that is all the available channels available at a node for VOD can be used up by neighbors and you may get an error msg that you can't play back your recording when you want to. Of course, a good deployment of SDV could mitigate this problem.
True, but the times that service may be out due to whatever It would be nice to know the program is still being recorded. Also would this allow for more recordings at once?
