CBS chief Les Moonves acknowledged Tuesday that "personality disputes between the different sides" in the writers' strike have become a significant factor in preventing a resolution. "I am hopeful. I'm not terribly optimistic," Moonves told an investors' conference in New York about the possibility of an imminent deal as the two sides resumed negotiations. The primary issue is the demand by writers for greater residual payments for television shows and movies distributed via the Internet. "We are trying to figure out what the world of new media will be. Hopefully, we can come to some resolution with them, that they can share in the pie," Moonves said. "Right now, we don't know what that pie is." Today's (Wednesday) trade publications indicated that the writers have proposed a scheme under which they would be compensated based on a graduated scale tied to the total number of viewers.
