PGCDemux/DGIndex audio delay report -- how to proceed?

[Gew]

Hiya!

This is a real newbisch question, yet I hope for your sympathy.
See, I've come to wonder, how shall I treat these delays?

Say for example that PGCDemux reports DVD audio -120ms.
I encode video -> MPEG-4 ASP; audio -> MP3.
Now, I am about to mux my A/V streams together with VDubMod.
Shall I "correct" the sync, here by adding "+120ms" for audio shift.
Or shall I enter the same value as PGCDemux reported, i.e. -120ms?

Enter as reported, -120ms.
