Query on AUGraph and AudioQueue

Hi All,
What is the difference between AUGraph and AudioQueue.
I am trying to play a AACplus file which I am able to play it in application with AUGraph but the same doesn't play in application with AudioQueue.

For AUGraph I am referring to the application "playfile" present under

/Developer/Examples/CoreAudio/SimpleSDK/PlayFile

For AudioQueue I am referring to the application "aqplay" present under

/Developer/Examples/CoreAudio/SimpleSDK/AudioQueueTools

Is it possible to play advance codecs with the help of AUGraph or some issue is there with the file.I tested out the specific aacplus file in QT it fails to play but it plays successfully in VLC and Fstream and on the playfile application mentioned above.Any suggestions,opinions would be of great help.
Thanks in advance.
Arnab
