How to append a simple text presentation at the beginning of a video file?

[Rodolfo Medina <rodolfo.medina@gmail.com>]

My apologizes to the listers for coming back to the same question I put in
another thread, but I couldn't really solve the problem.

I didn't get good results with Kino nor with the `cat' command.

If anyone experienced directly that matter, his/her help's very welcome.

Thanks
Rodolfo
