The home entertainment industry has divided into two camps regarding the format of writable DVDs.
The DVD-Forum, which includes companies like Philips, Sony, Hitachi, Mitsubishi, Pioneer and Toshiba, prefers the DVD-R and DVD-RW formats. The DVD+RW Alliance, consisting mostly of hardware and media manufacturers such as HP, Yamaha, Ricoh and Verbatim, backs DVD+R and DVD+RW formats.
Computer-based DVD burners can use any of the formats, but stand-alone DVD players/recorders are either one or the other. Currently, DVD-R has 42 percent of the market share for one-time writable media and DVD+R has 41. For re-recordable discs, DVD+RW leads DVD-RW by a margin of 58 percent to 33 percent.
The industry is also divided on the future format for recording high-definition video. The DVD-forum and several Hollywood studios prefer the HD-DVD format, while other industry players argue for the Blu-Ray Disc format, which offers 50 gigabytes of capacity compared to HD-DVD’s 30.
