The command lines contain "-qmin 1 -qmax 1 -target ntsc-dvd -c:a mp3"
Could you explain this combination?
(I thought mp3 is not supported for DVD's and I don't think 
you can / should combine constant quantiser with a target - 
how is the bitrate limitation supposed to work with this 
command line?)

Sorry if I miss something, I did not read through the 
whole old thread again.

Thank you, Carl Eugen
