Who supports which standard
In case you are in any doubt, each DVD standard maintains its own list of supporters from some of the most influential industry players.
DVD-RAM is backed by Hitachi, Toshiba, Panasonic and Samsung, and is also endorsed by the DVD Forum. DVD-RAM was the first standard developed by the DVD forum, and the first format used both in PC drives and in DVD recorders for the living room.
DVD-RW is also endorsed by the Forum, and is backed by Pioneer, NEC, Sharp and Thomson. This format also features in systems by Apple and Compaq. The Forum also supports the write-once DVD-R format, which is recognised as the DVD equivalent of CD-R media. This is the most versatile standard, as all DVD writers except the DVD+RW will operate with this format.
DVD+RW is not endorsed by the DVD Forum, but does have the support of the DVD+RW Alliance. This Alliance consists of Hewlett-Packard, Philips, Sony, Yamaha, Verbatim, Ricoh and Dell. Microsoft also announced its intention to join the DVD+RW alliance in February 2003. Like the DVD Forum, the DVD+RW Alliance has developed its own write-once format, DVD+R, which claims to offer a level of drive compatibility similar to that of DVD-R.
