Thanks for the suggestion, but it does not seem to be the case.  I ran
the command 

    vlc --intf dummy -vvv v4l:/dev/video:norm=ntsc:frequency=211250:size=320x240:channel=0:adev=/dev/dsp:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=800,ab=256,vt=800000,keyint=80,deinterlace}:std{access=udp,mux=ts,url=10.17.0.139}' --ttl 12

with and without deinterlace (as before, without works fine).
Curiously, without deinterlace seems to take more processor.  Typical
output from top with deinterlace:

    Cpu(s): 23.0% us,  4.8% sy,  0.0% ni, 71.7% id,  0.2% wa,  0.2% hi, 0.2% si

and without:

    Cpu(s): 39.8% us,  4.6% sy,  0.0% ni, 55.2% id,  0.0% wa,  0.2% hi,  0.2% si

The server has two 500 MHz Celerons.  However, I don't know how reliable
these numbers are, because no process is listed as consuming any
significant CPU, and vlc is listed as taking none.  This is a Debian
unstable system running Debian kernel 2.6.7-1-686-smp.

Again, there are no messages on the server or client after the programs
start.
