[M4IF Technotes] Mp4 files compatibility

[Bill May]

xvidenc does not correctly add a VOSH header, which has the profile
information.  mp4creator then defaults it to the highest profile
level.
QT 6.0 checks for that profile information, and won't play the profile
information.
mpeg4ip 0.9.7 version will display warning messages telling which headers
are missing.
In CVS on sourceforge, I have added an override command for the profile
which will become part of the 0.9.8 release of mpeg4ip; however, the
real fix would be to get XVID to add the correct VOSH header.
