I'm switching from Dtv to Cable and was curious as to how long I have before my HR10-250 and my Dtv DVR (Hr22 I think?) will allow me to finish watching the programming I've already recorded. Will they allow this indefenitly? Should I leave the sat connections in place or do I need to disconnect them before terminating my service? I just don't want to terminate my service and then loose the ability to watch the stuff I've recorded. It might take a few weeks to get to it all. Thanks!
