OK, firstly thanks for asking questions!
It is typed in the terminal, in the same directory as where you typed the commands shown in step three. (Creating the DVD file structure)
Since the source is not clearly specified, I shall assume that you mean the directory created in step three. That is specified in the synax in this format:
Code:
mkisofs -dvd-video -o <output iso file> <source directory>
And in this case the source directory is DVD, supposing you followed the guide exactly.
This depends on the capacity of your DVD, please specify if it is a DVD 5 or DVD 9.
Simply put, the final output size of the DVD depends on the what file you want on the DVD. There is control over it (you can do what you want with the files...).
Hmm... perhaps it is possible to do this by multiplying the amount of seconds of playback time your media (file) has by 1000 (the bitrate of the mencoder conversion, but this may not be exact), which would give you the possible (video) file size - then add this amount to the length of audio by the bitrate you are using. Once you have the size for the final one, perhaps you can multiply it according to what ffmpeg's bitrate is for the specifications you use. Maybe this will give you what you want. But if you do find a better, more accurate method, please share it
