A bus-mastering IDE controller can access data more quickly than a conventional IDE controller. Fortunately, most Pentium/PCI systems have bus-mastering IDE controllers. The trick is installing the correct driver software for enabling bus-mastering. Windows 95B (OS/R2) includes bus-mastering drivers, but Windows 95A does not. Typically, you can find upgraded drivers on a manufacturer’s website, including microsoft.com, intel.com, and compaq.com. Microsoft requires a bus-mastering IDE controller and driver for proper DVD-Video playback. If you do not install the bus-mastering driver, the DVD-ROM drive won’t always be able to send enough data. This will cause dropped or jerky video frames, noise, and audio problems. Because REALmagic Hollywood doesn’t bog down the Pentium, these problems typically don’t happen when viewing a movie, unless you move the mouse, use another program while the movie is playing, etc.
