DVD Knowledge: What is DVD and which DVD format should I use?
1. What is DVD?
DVD stands for Digital Versatile/Video Disc. It is an optical disc storage media format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs offer higher storage capacity than compact discs while having the same dimensions. DVDR stands for DVD Recordable and DVDRW for DVD Rewriteable.
A recordable DVD stores up to 2 hours of very good quality DVD-Video, including several audio tracks in formats like stereo, Dolby Digital or DTS and also advanced menu systems, subtitles and still pictures that can be played by many standalone DVD Players and most computer DVD-ROMs. If you choose to lower the video quality it is possible to store several hours video on a recordable DVD using low bitrates and low resolution with video quality more like VHS, SVHS, SVCD, CVD or VCD. It is also possible to have up to 4.37* GB ordinary data or mix DVD-Video and data on a recordable DVD that can be played by most computer DVD-ROMs.
There are many different formats: DVD+R, DVD+RW, DVD-R, DVD-RW, DVD-RAM, DVD-ROM, which DVD format is best for you?
2. Why 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.
