I saw a no return DVD rental stand at the San Jose airport. Seeing as US air has no entertainment decided to rent one. The dvd is packaged in seal plastic and they tell you several times not to open it till u are ready to view. It has unlimited viewing for 48 hrs, after which it self destructs. Interesting concept, anyone try it yet ? The only problem was, my laptop ran out of juice before the movie ended
