That sound you can hear is the studios dashing around as they look for a new scapegoat. Disney's got Redbox and Netflix in its sights as it declares plans to impose a 28-day window before it'll make its titles available for rental. Despite conceding that the studio hadn't seen any impact on overall DVD sales, CEO Bob Iger pointed to a 16 percent drop in quarterly revenue compared to 2010 as the motivation. It's also collecting splinters in its backside as it watches to see how well digital locker service UltraViolet fares with consumers before committing to join the program. Of course, given the legitimacy of First Sale Doctrine, it's possible Redbox will do as its done with Warner titles and just buy 'em at retail -- as long as it can cover its costs as it does so.
