Disney fans will be disappointed to hear that they won't be able to place preorders for DVDs of their favorite movies on Amazon anytime soon.

A restriction has been placed by the ecommerce giant on preorders for physical copies of some films from Disney due to a contract disagreement between the two companies, according to CNET. In the meantime, digital copies of films like "Muppets Most Wanted," "Captain America: The Winter Soldier," "Million Dollar Arm" and "Maleficent" can still be preordered.

The decision follows a similar move made by Amazon earlier this summer, which restricted preorders for discs of "The Lego Movie," "Transcendence," "300: Rise of an Empire" and other films from Warner Brothers.

People were able to preorder movies from Warner Bros. in late June after Amazon and Warner Home Video were reported to be close to reaching an agreement about their contract issues, PC Magazine reported.

Amazon's quest for a new deal with Disney is taking place alongside a similar conflict Amazon has been in with book publisher Hachette since May, CNET reported. The company said at the time that it restricted sales of books from the publisher because they couldn't agree on contract terms that would be mutually beneficial.

The conflict escalated last week when the New York Times published a letter Sunday that was signed by over 900 authors and urged readers to share their opinions of the disagreement with digital book prices with Jeff Bezos, CEO of Amazon, Chicago Tribune reported. Readers were also asked by Amazon last week to contact Michael Pietsch, CEO of Hachette, to share their opinions on the conflict.

"Just as paperbacks did not destroy book culture despite being ten times cheaper, neither will e-books," the company wrote in a letter on its website, readersunited.com. "We will never give up our fight for reasonable e-book prices."

Amazon also sent a letter to authors last month in which the company offered them all of the proceeds from e-book sales that take place during the conflict.
