My family has had a DVR for a few years now, and I've had one for many months, too.

Just today, I caught my sister watching an old favorite movie of ours, and asked her what channel it was on, only for her to say it was on-demand. I said, "Doesn't that cost money?", and she responded, "They have free stuff, too".

So right now I'm checking it out, watching a movie for free that I've been looking for our copy of for a long time.

It's just like digital movie rental. Except they have free movies. It's pretty cool. :)
