(I find this very difficult to understand, typical 
questions on this list are: "I tried ffmpeg -i input 
-c copy out.avi - see complete, uncut console output 
at the end of my email - how can I remux only the 
video?")

I may misunderstand your question - see above - but 
the following "removes" audio from the input file:
$ ffmpeg -i input -vcodec copy -an out.avi
