Encoding to Dolby Digital audio

[chrisb01]

Since I already have to extract the audio from the DivX AVI before authoring a DVD with DVDit, why don't I just go ahead and convert it to Dolby Digital format, which is what DVDit uses for compression. That way, DVDit won't have to compress it... it would save me a step.

Am I on the right track with this thinking.. can it be done? How? I haven't found any toold that would extract audio from DivX AVI and re-encode directly to Dolby Digital. Sort of the way VirtualDub goes decompresses the audio from the DivX AVIs and puts into uncompressed WAV.

That sounds right, I have heard that Sonic Foundry's soft encode can rpoduce dolby AC3 from various input files. However, knowing how good DVDit is, it wouldnt surprise me to see it re-encode the audio anyway!
