Why are there so many different formats for DVDs?

With so many different formats how do users know which DVD format is compatible with their existing systems, and why are there so many different formats for DVDs?
When DVD technology first appeared in households, users were simply popping DVD discs into their DVD players to watch movies — an attractive option to the then-conventional VCR. But just as compact disc (CD) technology evolved so that users could record and erase and re-record data onto compact discs, the same is now true of DVDs.
 
With so many different formats — DVD+R, DVD+RW, DVD-RAM, DVD-R, DVD-RW, DVD-ROM — how do users know which DVD format is compatible with their existing systems, and why are there so many different formats for DVDs? The following information sheds some light on DVD's different flavours, the differences between them and the incompatibility issues that the differing technologies have sprouted.
Key Terms To Understanding DVD Formats:DVD: Short for digital versatile disc or digital video disc, a type of optical disk technology similar to the CD-ROM.
DVD-Video: A video format for displaying full-length digital movies.
DVD-ROM: A type of read-only compact disc that can hold a minimum of 4.7GB (gigabytes), enough for a full-length movie.
burn: Slang term meaning to write data to a CD-ROM or DVD-ROM.
Divx: Short for Digital video express, a new DVD-ROM format promoted by several large Hollywood companies. With Divx, a movie (or other data) loaded onto a DVD-ROM is playable only during a specific time frame, typically two days. 
Why Are There So Many DVD Formats?
 
The crucial difference among the standards is based on which standards each manufacturer adheres to. Similar to the old VHS/Beta tape wars when VCRs first hit the markets, different manufacturers support different standards. Often called a format war, both the industry and consumers are still waiting to see which format will emerge as the industry standard.

 
 
Plus or Minus - What's The Difference?
 
The different variations on the term DVD (e.g. +R, -R, -ROM, and so on) describe the way data is stored on or written to the disc itself. These are called physical formats.

DVD+R and DVD+RW formats are supported by Philips, Sony, Hewlett-Packard, Dell, Ricoh, Yamaha and others.
DVD+R is a recordable DVD format similar to CD-R. A DVD+R can record data only once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time.
DVD+RW is a re-recordable format similar to CD-RW.  The data on a DVD+RW disc can be erased and recorded over numerous times without damaging the medium.Note: DVDs that have been made using a +R/+RW device can be read by most commercial DVD-ROM players. 
 
DVD-R, DVD-RW and DVD-RAM formats are supported by Panasonic, Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung and Sharp. These formats are also supported by the DVD Forum.

DVD-R is a recordable DVD format similar to CD-R and DVD+R. A DVD-R can record data only once and then the data becomes permanent on the disc. The disc cannot be recorded onto a second time. There also are two additional standards for DVD-R disks: DVD-RG for general use, and DVD-RA for authoring, which is used for mastering DVD video or data and is not typically available to the general public.
DVD-RW is a re-recordable format similar to CD-RW or DVD+RW. The data on a DVD-RW disc can be erased and recorded over numerous times without damaging the medium.  DVDs created by a -R/-RW device can be read by most commercial DVD-ROM players.
DVD-RAM discs can be recorded and erased repeatedly but are compatible only with devices manufactured by the companies that support the DVD-RAM format. DVD-RAM discs are typically housed in cartridges. 
DVD-ROM was the first DVD standard to hit the market and is a read-only format. The video or game content is burned onto the DVD once and the DVD will run on any DVD-ROM-equipped device. DVD-ROMs are similar to CDs.
 
DVD+R DL and DVD-R DL - Dual layer technology is supported by a range of manufacturers including Dell, HP, Verbatim, Philips, Sony, Yamaha and others. As the name suggests, dual layer technology provides two individual recordable layers on a single-sided DVD disc. Dual Layer is more commonly called Double Layer in the consumer market, and can be seen written as DVD+R DL or DVD-R DL.DVD+R DL (also called DVD+R9) is a Dual Layer writeable DVD+R.
DVD-R DL (also called DVD-R9) is a Dual Layer writeable DVD-R. The dual layered discs can hold 7.95GBThe dual layered discs (DVD+R9 and DVD-R9) can hold 7.95GB and double sided dual layer (called dvd-18) can hold 15.9GB.

A Note on DVD Burners:  Until 2003 consumers would have to choose a preferred DVD format and purchase the DVD media that was compatible with the specific DVD burner. In 2003 Sony introduced a multi-format DVD burner (also called a combo drive or DVD-Multi) and today many manufacturers offer multi-format DVD burners that are compatible with multiple DVD formats (as listed above).
 
Non-standardized DVD formats:DVD-VCD is a DVD-Video disc that has data on it that has been encoded by using the MPEG-1 video format with the same definitions VCD has.
DVD-SVCD is also not a valid DVD standard, since the DVD standard does not support the SVCD resolution. The term DVD-SVCD is used to describe a hacked, or non-standard DVD-Video disc that has SVCD compatible content on it.
DVD-MP3 is created with and contains only digital audio files in the MP3 format. Not all DVD players can play DVD-MP3 discs.
DVD-D is a disposable DVD format that provides a limited time play duration of up to 48 hours after the packaging has been opened. After the designated time has passed, DVD players are unable to read the disc. The packaging of the disc is airtight and the DVD itself has a special coating that begins to deteriorate when exposed to air. The DVD-D format is currently being used for video game and movie rentals where not only can intellectual property rights be better protected, but consumers have no need to worry about the hassle of DVD rental returns. According to the manufacturer's Web site, both the DVD-D disc and the cardboard packaging it comes in can be recycled.The DVD-D format was developed by German company FDD Technologies AG, and while no official definition of the D has been offered, many use the abbreviation to mean DVD-Destroy or DVD-Destruct.
