You already cancelled your Dish subscription? Too late. Access to those recordings will soon vanish. Binge it.
Those recordings are tied to your old account number, so resubscribing will not get them back.
Actually, if you just recently cancelled your subscription, and you still have your old Dish receivers, Dish will let you reopen your account with the same account number. You have to specifically request that, though, unless you are responding to a win-back offer from Dish that wants you to reopen your old account. In fact, with leased receivers, the only way the same subscriber could reactivate them is if they remain tied to the same account number. This is how win-back offers work. Dish does
not want to inconvenience or tick off subscribers who just cancelled and then immediately change their minds and want to come back. That subscriber has already proven once that they are willing to cancel their service. So, if they completely lose access to all of their DVR recordings, that may very well push them into cancelling again. If they cancel again soon enough, Dish may even have to let them out of any new contract that they had accepted. So, Dish gains nothing in such a scenario.
