No, only happens when you open a source video with AAC audio through an AVS file. Directly opening the source file won't induce the bug.
When you do so, ffmpeg2theora should report 6 channels instead of 2, and the resulting video will have chipmunk audio played through MPC-HC, and no audio at all when played in Firefox.
And I must use AVS, I want to hardsub the subtitles.
