Buffer the next show in on-line One Pass

Our home network gets busy enough with other traffic that sometimes we still lose stream. In some sense I wonder if that will always be true - I buy bandwidth at that tuned level to handle my other traffic plus being able to handle a stream most but not all of the time.

So I want my Tivo to download the next episode in a series I have marked as only coming from a stream. That way I can always watch the next episode without worrying that I will lose stream. it can automatically delete the episode from disk as soon as I have finished viewing it for all I care.

This is really the same request I've had since streaming services came into existence but now it's an improvement request on One Pass instead.
