StaxRip audio delay - am I doing it right?

[Vitality]

When ripping DVDs sometimes I will have an audio delay. I use StaxRip and DVD Shrink. One time, when StaxRip demuxed a VOB rip; it generated a file named "VTS_01_1 ID0 2ch 192Kbps -115ms.ac3". What I would do is set the audio delay from -115 or whatever number it is to 0. Is this the right way to do it, or leave it at -115 or whatever number?
