[MEncoder-users] mpeg2 split

[José Queiroz]

Well, as I said, when I used the "-force-avi-aspect" (and not -aspect
as I said first), the message disappeared. My question is much more
about the problem with the FOURCC code not appearing in the converted
movie, and if just using the "-ffourcc" flag can solve the problem.
