.3GP conversion

[abraxasDVD]

I have a file I am having prolems converting a file

GSpot reports the file as this:

File Type: 3GPP Media (.3GP) [MP4 compat.]
Mime Type: video/mp4
audio is blank

I used ImTOO 3GP Video Converter to convert to divx.
Summary:
Duration: 00:54:32
Bit Rate: 569kbps
Video:
Format: mpeg4
Size: 384x288
Frame rate: 25.00fps
Audio:
Format: mpeg4aac
Bit rate: 0kbps
Sample rate: 16000Hz
Channels: stereo

Gspot now reports it as

Codec : 0x0055(MP3, ISO) MPEG-2 Layer 3
16000Hz 64 kb/s total (2 chnls)

Is there a way just change the Audio bit rate and/or Sample rate as the video is fine its that the sound is being played slow. Without encoding the whole thing again.

virtualdub
video->direct stream copy
audio->full processing
audio->conversion
audio->compress mp3
file save avi.

if it wont work try convert the audio from the 3gp to wav with goldwave and then use it virtualdub, audio->wav audio.
