Re: Re: This is not a rumour - it was confirmed at the quicktime keynote at WWDC
See, what we have is format wars here. The problem with AAC in this case is that it's not Dolby Digital. And that is what multichannel speakersets decode. So if you have a 6 channel AAC file, it must be transcoded into Dolby Digital before the speakers can process the signal.
Fortunately, AAC and DD are practically the same format! AAC is really a more advanced form of Dolby Digital, which are both from Dolby. Nice, huh?

Wouldn't software have to decode first? Meaning Optical out has all the information for a decoder to work off of (like info from a DVD).
But if AAC has 6 distinct channels, it has already been decoded.
