I have Comcast in the US and On Demand allows you to watch most movies, series, and special for free.
Of course it lets watch them when you want.
You can stop, pause, rewind, and fast forward and all done without a DVR.
This puts satellite to shame. It also turns the pay per view model upside down.
PPV still cost the same on On Demand but why order a movie at predetermined time when can order it when you want it.
They still have commercials or promos on some shows. I watched the Chappelle show and it had plugs for other Comedy Central shows BEFORE and AFTER it.
You must have a digital box though so no hacking (yet_.
