There's no grace period on a cancelled unit. Any recordings that exist already *should be* viewable, but I doubt the SP list & To Do List will survive. There's a small, but possible, risk that cancelling, then re-subscribing, could assign the unit a different Media Access Key, that *could* "bork" everything. If it's the only TiVo on the account, the possibility of the MAK being changed, is much more likely, than if there were others on the account (since the MAK is the same on all units on an account). With just about any company, except TiVo, I'd suggest asking them about it. She can still ask, but TiVo tends to say one thing, then do something very opposite what they tell you. I speak from experience, and reading what others post, as well. I'll defer to the other qualified folks to hopefully be more helpful.
