Dolby Digital EX creates six full-bandwidth output channels from 5.1-channel sources. This is
done using a matrix decoder that derives three surround channels from the two in the original
recording. For best results, Dolby Digital EX should be used with movies soundtracks recorded
with Dolby Digital Surround EX.
