I apologize in advance if this has been asked before. I know how upset some people get about such matters, but I can't seem to find the info I would like. Let's assume there is a storm in the area, and satellite signal has been lost (we all know how frustrating that can be, even if only temporarily). Is there a way to access the 622 DVR recorded material? I have tried to no avail on more than one occasion. It would seem to me that a satellite signal would have no effect on the stuff already on the receiver. What am I missing? Any input appreciated.
