What is the MPEG-2 ?
An MPEG-2 decoder is needed to play DVD-Video titles plus any MPEG video contained on a DVD-ROM disc. Both hardware and software decoders are available. Hardware decoders allow a slower processor, such as a Pentium 133, to be used. Most decoders include a video output, which allows your favorite movies to be watched on a TV instead of the computer monitor. Software decoders require a faster processor (at least a 266MHz Pentium II) and a suitable graphics card, but offer a lower cost solution for PCs already equipped with a fast processor. DVD add-on kits usually comprise a DVD-ROM drive and MPEG-2 decoder board. Software to play DVD-Video discs is also included in the package. Normally this includes an on-screen controller to simulate the remote control of a DVD-Video player.
