When your digital movie is removed from the store...

[Kochore]

I know that it stays in your account if you buy it before it's gone but, do you still risk losing it somehow? Will they eventually pull that title from your account itself? Or does nothing change despite it being removed from the store?

Had a title in my collection that got pulled from both iTunes and VUDU store, but for some reason, won't play on my Apple TV. So now, I'm curious.
