[MPlayer-users] How set bitrate?

[Lugo Teehalt]

Trying to play an *.mp4 file, it jumps and the sound is very odd.  I think the bitrate for the sound is wrong.  How do I set it?

Output of 'file':
moneyAsDebt.mp4: ISO Media, MPEG v4 system, version 1

Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)         
FAAD: compressed input bitrate missing, assuming 128kbit/s!               
AUDIO: 44100 Hz, 2 ch, s16le, 128.0 kbit/9.07% (ratio: 16000->176400)     
Selected audio codec: [faad] afm: faad (FAAD AAC (MPEG-2/MPEG-4 Audio) decoder)

Don't think it's 128.0 kbit bitrate; did work out what it should be but have forgotten how - so it anybody knows ....

How set correct audio bitrate? I'm so incompetent that I can't work out how to reply to this forum, unless someone tells me, but thanks any help.
