Some technical approvals are delaying the launch services related to on-demand burning of DVDs, reports VideoBusiness. Earlier this year Hollywood studios approved the CSS lock on DVDs burned on a PC or at as retail kiosk. The lock, known as “content scrambling system,” or CSS, comes standard on prerecorded DVDs today, and matches the descramblers on DVD players. But online movie download services such as Movielink, CinemaNow and Amazon.com’s Unbox haven’t been able to use CSS because studios fear widespread DVD burning could lead to piracy.

After approval, the service was supposed to be launched by end of April, but that didn’t happen, and may now be pushed back to end of June at the latest, the story says. The studios and service have been waiting for final amendments to the Content Scrambling System license to be approved by the DVD Copy Control Assn., the administrator of CSS, so that they can move ahead with download-to-burn offerings for consumers.
