Limitations of optical out and 5.1 sound channels

Looks like it doesn't quite work that way, unfortunately.
I remember reading in the documentation the Handbrake video encoding program, that there are limitations in QuickTime and the Mac OS Core Audio system that prevent sending 5.1 discrete channels over the optical out. Its possible with some analogue devices but not the mac's optical connection.
