Have you tried including those values?  I've had some success on damage 
files with rather long analyzeduration and probesize options, see the doc 
for details.

Not that I think it will make a difference, but it's always good to try the 
latest ffmpeg available (at all, not just packaged for your platform).

Also, "copy" does not re-encode but it should re-mux.
