CinemaNow is now offering the ability to download movies to your computer and watch them. You also have the option to burn the movie to a DVD disc that can be played in a standard DVD player. Then if want to you can also download and a label and cover art for that movie.
The movies cost between $9 to $14 each, and right now the selection of movies is limited (about 100+ movies). Hopefully if the service takes off, they will continue to expand their collection.
