I don't fully understand those download services. Maybe someone here could ed-u-ma-cate me.

When you download a movie, you have just bought it right? How to you keep it for future use? Do you have to play it thru THEIR player or equipment? I know it has to be DRM infested.

And how is the quality? It can't be as good as a DVD, or it would take a week to get, and that would be on a fast network. Dial up may take a few months to get.

Do you use a service like this and do you like it?

well they rather rent everything out or lease it, so they retain full control.

Just another agreement between two companies.

On XBL you are really only renting the movies. You have to view it within 15 days of downloading and once you press play you can watch it for one day. You can keep it on your hard drive if you want but would have to pay to watch it again after the one day. As for quality, it is great. Full HD on some, 480P on all. In my experience, an HD movie takes about an hour to download on my cable internet connection, although you can usually start watching it while it continues to download. Usually the play option comes up after about 5% is downloaded. I have only downloaded 720P widescreen movies myself but I assume that the 480P movies would take considerable less time.
