Test files (22050 Hz.rar)
For the .flv in file informations it say 44100 Hz instead of 22050 Hz.
PS: The .aac file extracted using export => raw audio (the .flv was opened with ADTS headers) is different from the file extracted from FLV Extract.

Thanks, I am looking into it.

There are two factors making these streams different.
The id bit in the ADTS header extracted from VirtualDub is incorrect. It should be '0' instead of '1'. I will fix that bug in the next releases of the FLV and Matroska plugins. I will also update the text in the extended options dialogs; I agree with you that it is confusing.
The stream extracted from VirtualDub is shorter because VirtualDub has cut off the audio to match the video duration. To avoid this, go to the Video / Select Range dialog and uncheck the box which says "Cut off audio when video stream ends". (I hate that box.)
The audio has implicit SBR and is meant to be played back at 44100 Hz.

I've uploaded new versions of the FLV and Matroska plugins to fix the ADTS bug:
http://fcchandler.home.comcast.net/Plugins/FLV
http://fcchandler.home.comcast.net/Plugins/Matroska
Note that this fix makes them incompatible with versions of AACACM prior to 1.5, so you will need to upgrade him as well:
http://fcchandler.home.comcast.net/AACACM
And with that, unless something catastrophic is found, I'm done for this weekend.
