The coaches' film is only available on select plays. Click on the "plays" tab and there it gives you the option to view the coaches' film or broadcast on certain plays (i.e.: a sack, int, or touchdown play). You'll probably have to wait a couple days to see the coaches' film for the Browns game.
Hey, brother... it isn't something you turn on, the web site turns them on, usually by Wednesday, on selected plays. You access the selected plays through the 'plays list'. The plays will have a caption denoting them as 'coaches plays'. They full and wide angle views from above and from in front - very cool stuff.
