Signed up for sky by Broadband which, as I am a sky movies subscriber, allows me to download said movies and watch them on my computer. The selection of movies is similar to the current selection on sky so it's kinda ok, not so bad that I ever get around to unsubscribing.
Sky By Broadband itself is heavily Microsoft DRMed but I don't really care. The files are circa 500M and they can be backed up to cd/dvd but you can only play them back on the pc you record them on. The licences to watch the films are time limited but the time limits are in the order of months. You have to download the whole film before you can watch it so it's not quite video on demand.
You are only allowed to register one pc in a household: I don't know if it's using my mac address to enforce this or what happens if the pc breaks and I want to use another one.
Still, it's costing me no extra and I can watch the films anywhere in the house and, in fact, anywhere as I can watch them while disconnected from the internet, such as when on holiday.
Oh, it covers Sky Sports as well but I guess from the themes on this site you can guess I'm not a big sports fan.

i too have signed up for sky by broadband and was frankly a bit disappointed with the selection--i have downloaded 4 movies--but i expected a similar choice to what was being shown on sky at the mo. as i don't have sky plus i was hoping it would give me that benefit.but thanks for telling me you can back up to disc, can you watch them after your 30 days or whatever?
