New this week on DVD and Blu-ray:
"The Hobbit: The Desolation of Smaug" - Bilbo Baggins continues on his journey with Gandalf and the dwarves in the second of three films Peter Jackson is making based on J.R.R. Tolkien's "The Hobbit."
Extras include production videos, the featurettes "Peter Jackson Invites You to the Set" and "New Zealand: Home of Middle-Earth, Part 2" and a music video for Ed Sheeran's "I See Fire," but fans will have to wait for the extended edition and bountiful extras that normally accompany Jackson's "Rings" / ''Hobbit" films. (Warner Home Video, $28.98 DVD, $35.99 Blu-ray/DVD/digital copy, $44.95 3D Blu-ray/Blu-ray/DVD/digital copy)
"August: Osage County" - Meryl Streep and Julia Roberts both received Oscar nominations and lead a talented cast (Ewan McGregor, Chris Cooper, Abigail Breslin, Benedict Cumberbatch, Juliette Lewis, Dermot Mulroney, Sam Shepard) in this adaptation of Tracy Letts' Pulitzer Prize-winning play. Director John Wells is joined by cinematographer Adriano Goldman for a commentary track. Other extras include deleted scenes (with commentary), a making-of featurette and a writing featurette with Letts. (Anchor Bay, $29.98 DVD, $39.99 Blu-ray)
"Grudge Match" - Sylvester Stallone and Robert De Niro play former rivals who agree to get in the ring 30 year later in a boxing film that failed to deliver a knockout in theaters over Christmas.

Extras include an alternate opening, an alternate ending, deleted scenes and the featurettes "The Bull & the Stallion," "In the Ring with Kevin Hart," "Ringside with Tyson and Holyfield" and "Blow for Blow with Larry Holmes: Kevin Hart Unedited."

"Justin Bieber's Believe" - This documentary mixes concert and behind-the-scenes footage of Justin Bieber. I'm guessing there is no egg-throwing footage. Extras include deleted / extended scenes. (Universal Studios Home Entertainment, $29.98 DVD, $34.98 Blu-ray)
"Paranormal Activity: The Marked Ones" - The latest installment in this found-footage horror franchise focuses on a young Hispanic man who starts experiencing strange things after the death of a neighbor.

"Nurse" - Paz de la Huerta plays a caregiver by day, sexual predator at night. Usually she stalks unfaithful men, but she becomes obsessed with a fellow nurse (Katrina Bowden) in this horror-thriller costarring Corbin Bleu and Judd Nelson. Director Douglas Aarniokoski delivers a commentary track, and the disc also includes a making-of featurette and video diaries by Bowden and Bleu.
