Not really. It depends on what program you use to mux. For example
mkvmerge leaves about 4 KB of data at the beggining in case it needs to
write some more stuff later. Usually this space is not used. So
modifying mkvmerge might allow saving a little more space. Other muxers
may have similar things too. I think AVI-Mux GUI (from Alex Noé) is the
most flexible for that.
