Let me understand clearly.

You are downloading a multipart binary from Usenet.  You get something 
like yyy.avi.001 yyy.avi.002 yyy.avi.003 in your saved directory, 
correct? (I was going to use xxx but I thought that was suggesting 
something.) ;)

Now if this is correct, then all you have to do is cat them together. 
  I have done this for years.  Now to compound things, I have found 
that  if and .avi file is missing a segment, and it of some certain 
formats, it won't play past the missing segment.  I have run across 
the same problem with .wmv files.  I wrote a simple script but it 
won't work with files that have spaces in their names.

Now if you look at the instructions for mencoder, there is a method 
that will join avi segments and process the index.  It works 
sometimes.  I did have a command that would repair avi's and process 
avi segments using mencoder but I lost it during the xmas cleanup.  I 
shouldn't have relied on a sticky note to stay around.

Also if you have a problem with a file, using mplayer -idx filename 
sometimes helps as well.

Mplayer is a nice tool but I found that avifile that was on RH 6 was 
great as it would play almost any segment of a file which I cannot get 
mplayer to do.  It could have something to do with the codec of the avi.

Look at the mplayer/mencoder documentation.
