Thank you for the feedback. Now I see where I can change the settings
and clearly the default settings are not the most optimal. Changing the
video bitrate to 9000 improved the video quality significantly (I think
the limit is around 9800 but I thought 9000 would be safe). I also
needed to change the fps for NTSC. However, I'm lost with the other
settings. What is quantisation? I don't know what the valid values are.
I'm really not an expert with DVD settings and I see a lot of settings
available with this format. The default settings definitely need to be
changed to provide the most optimal results and by someone who really
understands how the different values affect the video quality.
Unfortunately the audio got messed up. The resulting audio is very
intermittent and is obviously not ok. Again, I'm not sure what settings
to change to fix the problem.
The good news: With the new video settings I was able to import the file
in DVD Styler. I think DVD Styler doesn't compress again. I'm almost
sure it recognizes the MPEG format and it just creates the image to
burn. It did it way too fast to think that it compressed the video

Maybe give "DeVeDe" a shot. It's one of the few programs that has a
simple-enough-no-bullsh.. UI (in my opinion) and seemed to work well for
me in the past. It also has an option to tell it that the file is
"already in a MPEG-PS format, ready to be put on a DVD" so that you
avoid compressing a third time.

First, in the "advanced" properties of mpeg2enc, I see that the default
setting for the format is "Generic MPEG-1". This is, obviously, complete
crap. It should be "DVD MPEG-2".
Then, there is the "bitrate" setting and the "quantisation" setting you
probably want to experiment with... I'd be curious if you can report
your findings, maybe your experience (if successful) should become part
of the user manual...
