Claiming Disney allowed its movies to be sold on other services during an exclusive deal with Starz, the Liberty Media property has sued Disney, reports CNET.
The apple of contention is a 2005 agreement between the two parties that made Disney movies available for online sale exclusively through Starz. Disney has violated that deal, according to Liberty Media Holdings, by making the movies available for sale through Apple's iTunes and Wal-Mart's download site.

Starz execs say they raised the issue with Disney on multiple occasions but found no relief as a result of those meetings.

Disney has predicted $25 million in revenue from the sale of movies via iTunes in the first year of their availability.
