Plus Wizard Forces ES(audio+video)

[ln108]

I've just downloaded TMPGEnc Plus, and I'm trying it out. This would be a newbie question, therefore.

The wizard for making DVD forces the output option to ES(audio+video), making separate video (m2v) and audio (wav) files. Why this behavior? Why not just make a mpg file?

Is this option somehow the preferred option for DVD authoring? If so, why? I plan to use Nero 6 to make the DVD.

Thanks!

Most authoring apps (AFAIK all do) de-mux the two anyway, so why not start out like that. Saves timee later and provides greater sync accuracy. btw, Others may disagree, but I think the wizard stinks.
