[Mp4-tech] problems with encoding MP4 files using MP4Enc. Can anyone help?

[Anthony Kavassis]

Greetings to all,
MP4Enc has been giving me this very troublesome error and I can't seem to 
find out why its happening. Has anyone had this error cropping up:
No Mux info for stream no 0
and if yes does anyone have the solution?
Regards,
Anthony
I'm including the script file I'm using (included in the samples directory 
of MPEG-J):
