Media Sources Tab (Fig. 10)
Media Sources define the music files available to the user and the configuration of the
audio outputs from the host PC. Windows Media Player is the resident music archiving
software and is included with XP, Vista, or Window's XP Media Center operating
systems. That will appear by default under the Select Media Source header. If you have
downloaded iTunes, it will appear as well. If you intend to use more than 1 audio output
from the PC, make sure that "Split in Multiple Channels?" is set at "True". This will
convert the audio output configuration from surround to multiple stereo streams.
