It's for a cinema that plays movies (pay-per-view), so I need to count the minutes from the movie begins to the user exits.

At the web you can only make some guesses how long a user stays on a page. You never will get feedback if the user simply goes elsewhere or closes the browser. For pay per view (in your case for time) you may - use a specialized application to play the video (not user friendly :) - force the user to do something to keep the video stream alive (also not user friendly :) First do a decision about which way you ensure pay-per-time then think about the implementation. An option would be of course pay-per-view without time limitation. Regards, Frank
