Wikipedia kertoo studioiden formaattituesta seuraavaa:
In terms of major studios in North America, HD DVD is currently exclusively backed by Universal Studios (including subsidiaries Focus Features and Rogue Pictures), Paramount Pictures (including Paramount Vantage, Nickelodeon Movies, MTV Films, DreamWorks Pictures and DreamWorks Animation), The Weinstein Company (including Dimension Films), and First Look Studios.
The format is non-exclusively backed by Warner Bros. Pictures (it should be noted that a number of Warner's titles—Batman Begins, Constantine, Troy (excluding Troy: Director's Cut), V for Vendetta, The Perfect Storm, Poseidon, The Matrix Trilogy—are HD DVD exclusive at the present), New Line Cinema (it should be noted that some of New Line Cinema titles, the first being Hairspray, are announced as Blu-ray exclusive for limited time due to lack of region coding in HD DVD.[67][68] [69] All catalog titles will be released simultaneously in both formats), HBO, and Image Entertainment (including the Discovery Channel),[70] Magnolia Pictures,[71] Brentwood Home Video, Ryko, Koch/Goldhil Entertainment.[72]
Joku studiohan hyppäsi hiljattain BR -leiristä HD -leiriin, ilmeisesti aika mukavaa summaa vastaan.
HD on muuten tällä hetkellä aluekoodivapaa. Mahdollisuus koodin käyttämiseen on, mutta sitä ei ainakaan toistaiseksi käytetä.
