    I have several episodes of an anime in an avi wrapper, but oddly, they are encodec in Windows Media Video and have AAC audio. I want to convert them to XviDs with MP3 audio. I tried to find a program to do it, but none could decode the AAC. I thought I might have to demux the AAC and convert it with another program, but I can't find a program that can do that either.

    any suggestions?

    Your right that is an odd combo. Wonder why they didn't use mkv as a container?

    Anyway I would suggest that you demux it the same way that it was most likely muxed and that would be with AVIMuxGUI.

    I tried the right click->extract to ADTS packed AAC file, and it just produced an empty .aac file. When I click start, it just makes the same .avi file from before. So this isn't working either, what should I try next?

    Well I think there are a couple of GUI's for ffmpeg. Not sure if any have installers though and they are most likely aimed at specific functions. ffmpeg has a lot of different options making it hard to make a GUI that covers all of them. For instance there is a simple GUI purely for AC3 encoding.

    i was too lazy to look for avimux so i remux it using mkvtoolnix and then extract. :)

    You don't. It just outputs whatever streams are in the mkv.

    well, the problem here is the aac audio. vdub don't recognize it.
    and so on.

    so what you need to do is demux the aac, with anyway you like. and decode with faad2 decoder. or simply with any audio encoder, example dbpoweramp to wav.

    the problem is that i can't find a program that will demux the AAC. if i can't get it demuxed, then i can't convert it, so therefore, mkvtoolnix is useless for this purpose.

    please, i need a name of a program that can demux AAC.

    What do you mean if you can't demux you can't convert? There is no need to demux to convert. I just tried AVIMuxGUI and was able to demux aac fine anyway. Also with mplayer I was able to decode the audio using -ao pcm -vo null -vc dummy; no need to demux. Could also use mencoder with -oac mp3lame -ovc xvid to convert.

    as I had said before, I couldn't get AviMuxGUI to work for me, but I've got mencoder working on it right now and I'll let you guys know how it turns out.

    after some failed attempts with mencoder trying to get it to do everything (think it was the GUI's fault), i decided to just extract the aac to a wav file, convert to mp3 with Nero, and then mux it and finish the job with VirtualDubMod.

    everything is working fine, thanks for the help.
