This appears to be happening because the file is encrypted but not compressed.  
The
method of working out the encryption key I am using (based on stormlib) only 
works if
the file is compressed.

Ladik's MPQ Editor shows the key as unknown in its Name Breaker screen, but is 
still
able to decrypt it.  I wish I knew how.

I will keep looking into it.

I have found a fix.  It involves guessing the first 8 bytes of the file based 
on its
extension.

I have made a lot of changes to the code in the process so it will take me a 
while to
merge it with the current version in svn.

I also found the same issue with "staredit\wav\combeep0.wav" in Starcraft's
"maps\campaign\(1)Enslavers01.scm" so I've used that as a double-check for the 
new code.

Glad to hear that. And that's what mpqeditor does?

I don't know how mpqeditor does it.  This method is my own invention.

This should now be fixed (svn revision 9).
