What is "realmagic"

RealMagic (or ReelMagic), from Sigma Designs, was one of the first fully compliant MPEG playback boards on the market in the mid-1990s.

RealMagic is a hardware-accelerated MPEG decoder that mixes its video stream into a computer video card's output through the video card's feature connector. It is also a SoundBlaster-compatible sound card.
