Quicktime didn't read pystel mp4

I encoded some track with psytel encoder (2.15) and convert them in mp4 with mp4 creator.  When i tried to play them with QT player, i got an error msg saying my file have some invalid mpeg-4 audio data and an audio decoder is corrupted "Expected object type=audio(0x40); found objet type=^0 instead" ??? 

What i did wrong or it's normal that QT can't read those files due to mpeg standard broken  ??

Psytel creates MPEG-2 AAC files, while QT expects MPEG-4 AAC files. You should get the MPEG-4 version of Psytel aacenc.

Menno

EDIT: Psytel creates MPEG-2 AAC files not 4

should be MPEG-2 for Psytel. There is a MPEG-4 version of aacenc also, BTW.
