I don't know. Maybe something got re-encoded by accident?
-- Either a bad project setting in DVDWS2 (accident),
-- or the input MPEG was not 100% to the NTSC/PAL specs as it needs to be (not an accident per se, but rather something you were not aware of).
Authoring should only take 15 minutes, if you have a still menu, and are creating a single-layer DVD-Video. If it takes longer than 45+ minutes (often many hours), it's re-encoding. Only when motion menus are involved, would it take an average 30-45 minutes.
You can't trust the filesize meter in DVDWS2 (or any other authoring app, for that matter). Look at your assets, and see how big the files are.

MPV is video only.
MPG is just an MPEG container, usually video+audio. (Sometimes just audio, sometimes just video).
AC3 is Dolby audio
Not the same.
We've gone over this before in other posts in the past:

You never "open" audio or video in DVDWS2. The only thing that can be "opened" is a project file.

You import audio and video into the various asset libraries, as shown in
the DVDWS2 guide. Audio can also be separate imported through the audio tab, when the video file is imported properly on the asset timeline, and you're in edit mode. I know that sounds complex, but it's been
explained in past posts -- in the video guide, I believe.
