DVD-VR

The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media. As opposed to media recorded with the DVD+VR recording standard, the resulting media are not DVD-Video compliant, and will not play back in some DVD-Video players. Most DVD video recorders in the market that support DVD-R, DVD-RW, or DVD-RAM media will allow recording to these media in DVD-VR mode, as well as in a DVD-Video compliant mode. It is possible to use the DVD-VR format with DVD+R and DVD+RW media, but no examples are known other than some PC based recording utilities.

The standard was introduced in 1999 by the DVD Forum, and licensing is managed by the DVD Format/Logo Licensing Corporation . For each of the supported media, the full recording standard consists of three parts being: Physical Specifications (Part 1), File System Specifications (Part 2), and the Video Recording Specifications (Part 3).
