NOTE: If you simply want to convert FLV to AVI including audio, the FLV Input Plugin for VirtualDub (see below) is most likely a better choice. FLV Extract currently writes out separate video/audio files which you would have to join. Also, FLV Input Plugin is able to maintain synch in variable framerate videos by inserting drop frames. However, it doesn't yet support H.264 or AAC.
NOTE: The AVIs will not play unless you have the right decoders. ffdshow-tryouts can decode FLV1, VP6F, and H.264; make sure they're enabled in its configuration dialog.
NOTE: The extracted MP3s may appear to have an incorrect duration in your audio player. This is because FLV Extract doesn't generate a VBR header, but the files are perfectly valid nonetheless. To add a VBR header you can load an MP3 in foobar2000, right click on it, go to Utils, and click "Fix VBR MP3 Header".
