Do you have the original source material to perform encoding from?
I tried a brief experiment on a .mpg file - I used "dd" to cut a section
from the middle of the file (attempting to simulate the 'hacked apart'
you mention). Then I used mplayer to dump the video stream.
dd if=foo.mpg of=bar.mpg skip=23 bs=2k count=100
mplayer -dumpvideo bar.mpg
the file 'stream.dump' was correctly recognized as a MPEG-ES stream
suitable for use with mplex.
If that method does not work for you then, alas, reencoding I think
is the only way to salvage the situation.
Good Luck!
