I have a Matroska video with AAC MPEG2/LC audio. I want to convert the audio to AC3 to encode the video for DVD. Simply demuxing the audio using VirtualDubMod and encoding it with dBPowerAmp Music Converter (with the MP4/AAC decoding codec) doesn't work. What encoding programs do I need to extract and convert the audio?
You can extract the AAC audio from the MKV by using mkvextract from command line ( CLI ). Its coming with the mkvtoolnix 1.4.0 installer from http://mkvmerge.matroska.org Easiest way, however, is to use TMPGencoder to convert video and audio from the MKV file into MPEG2 video and MP2 audio, TMPG has a built in MP2 audio encoder to do that, and MP2 audio is part of the DVD specs also.

It's a shame that mkvextract doesn't have a dedicated GUI of its own. I'll be using mkvextract a lot since I use AviSynth to frameserve to TMPGEnc 3.0 Xpress. Thank you very much for your help anyway.
Try this one : http://forum.doom9.org/showthread.php?s=&threadid=73819&highlight=mkvextract Its a third party tool, but was reported to us as being quite stable and usable. Christian matroska project admin http://www.matroska.org
