The Power Macintosh or Macintosh Performa 6360, 5400 series, and 6400 series Power Macintosh come with built-in video support. These computers also have support for video editing, the TV Tuner Card, and the FM/TV Tuner Card. Because the video digitizer is tied to the built-in video on these computers, there are two situations of which you should be aware:
1) If a PCI video card is added, and the built-in video is not used at all (that is, there is nothing connected to the built-in video connector):
The video digitizer will not initialize on startup and will not be available to applications such as Apple Video Player and Apple FM Radio. Apple Video Player, Apple FM Radio, Avid Cinema, and any other application requiring the video digitizer will not function when the built-in video connector is not being used.
2) If a PCI video card and built-in video are being used simultaneously (there are two monitors connected to the computer):
Apple Video Player will launch, but will perform much better when the video window is on the monitor connected to the built-in video connector. Apple FM Radio will work with no problems (assuming the FM/TV Tuner Card is installed). Avid Cinema will work with no problems (assuming the Avid Cinema hardware and software are installed) as long as the monitor connected to the built-in video connector is the monitor with the menu bar. The menu bar must be on this monitor when the computer is started up. To change the location of the menu bar, open the Monitors & Sound control panel and click the Arrange button.
