Coinstar Inc., owner of the Redbox DVD-rental machines, said it hasn’t agreed to Time Warner Inc.’s effort to double a 28-day delay in making new Warner Bros. movies available for rental.

No revised terms have been reached, Coinstar said yesterday in an e-mailed statement, referring to reports that said a new accord with Warner Bros. established a 56-day delay for new movies. A deal for a 28-day delay on new films expires Jan. 31, according to a Coinstar spokeswoman.

Coinstar relies more on new releases than competing services like Netflix because the Redbox kiosk limits the number of movies offered.

Coinstar, which operated about 34,400 DVD rental kiosks as of Dec. 1, fell 5.5 percent to close at $40.98. Shares declined 19 percent last year.
