Paul, surely you remember my software ac3jack? It uses the AC3
(dolby digital) encoding from the FFMPEG library. Legality
slightly questionable, but it works.
I need to make some efficiency improvements, but if someone
actually uses it, my incentive to do so increases.

Helge, what paul is saying here is that it has a basic capability
to pan a track to more than 2 channels but it isn't particularly
well suited for 5.1. Primarily, the interaction between the
left, center, and right will probably be difficult to get right
with ardour's default 2d panners. For a music production I would
simply ignore the LFE channel entirely anyway, it is rarely used
even by professionals for music.
