[streaming] intermittent audio stream

Greetings,

I'm trying to stream a V4L stream with the following command:

vlc --color v4l:/dev/video0:norm=ntsc:frequency=77250:size=640x480:adev=/dev/dsp:audio=0 
    --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=512,ab=128,deinterlace}:std{access=mmsh,dst=:8080}' 
    --ttl 12 -I dummy

And I'm successfully receiving the video portion with:

vlc mmsh://hostname:8080

The problem is that audio (from the line-in) goes in and out. 

Here are the client's error messages:

main warning: buffer is [big number] in advance, triggering downsampling
main warning: timing screwed, stopping resampling
main warning: audio drift is too big [negative number], clearing out

The client and server are on separate Linux 2.6.20 machines.

The server is 0.8.6c, and the client is 0.8.6d.

How can I fix the choppy audio? It plays. But is choppy.
