It won't. The fancy stuff just sets the video pixel aspect ratio to be
ntsc widesrceen, and sets the language descriptor for the audio stream
to english. That doesn't make any difference whatsoever concerning the
audio encoding/muxing/playback, which was your main concern iirc.

The reason I posted this is to show that I got a QT 7.2. compatible
mp4 stream with really standard faac encoding and mp4 muxing options.

If that does not work for you, a possible reason could be the software
versions you are using. I have here
MEncoder dev-SVN-r26708-4.2.3
MP4Box - GPAC version 0.4.4
FAAC 1.26.1 (Nov 13 2007)
where faac would mean the library/dll version your mencoder links to.

Apart from that, you could supply some more information (gpac, faac,
QT versions, error messages etc.) if you want help on the issue.
