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 do 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 record 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.
