DVD, also known as Digital Versatile Disc or Digital Video Disc, is an ocular disc storage media format, mostly used for video and data storage. Physically DVDs are of the same size as compact discs (CDs), but has a much larger storage capacity.
DVD-ROM (read only memory) refers to DVDs that have data that can only be read and not written; DVD-R and DVD+R (recordable) can record data only once, and then function as a DVD-ROM; DVD-RW (re-writable), DVD+RW, and DVD-RAM (random access memory) can all record and erase data multiple times.
DVDs are of high quality and are transferred without difficulty to a computer; however, the large file sizes and ambiguous file names are some disadvantages to using a DVD. Converting a DVD to an AVI or MPEG file provides benefits such as small and portable file sizes and your own file naming. Also, the files can be used for video editing.
Converting a DVD to AVI will prevent issues which may arise if the DVD was copied in another format; these include reduced quality and limited capacity which can result from using a DVD burner. The conversion can be done by software programs such as DVDx, Fairuse Wizard, avi.Net, and Nero.
