Selecting DVD titles in megui

[martok604]

Hello all,

Due to the 5.1 audio bug in Recode, I am looking at
alternatives for encoding to mpeg4. I've come upon megui
which looks promising but am having trouble selecting a DVD
title. The guides that be say to select the first
vob in a titleset and all vobs automatically get imported.
However, I have an episodic DVD (Buffy if it matters) with
four eps per disc. The structure looks like this.

VIDEO_TS.BUP VIDEO_TS.IFO VIDEO_TS.VOB VTS_01_0.BUP
VTS_01_0.IFO VTS_01_0.VOB VTS_01_1.VOB VTS_02_0.BUP
VTS_02_0.IFO VTS_02_1.VOB VTS_03_0.BUP VTS_03_0.IFO
VTS_03_0.VOB VTS_03_1.VOB VTS_03_2.VOB VTS_03_3.VOB
VTS_03_4.VOB VTS_03_5.VOB VTS_03_6.VOB VTS_03_7.VOB
VTS_04_0.BUP VTS_04_0.IFO VTS_04_0.VOB VTS_04_1.VOB

So though there are four titles on the disc looking at it
from recode, all of the content would seem to be in
vts_03. VTS_02_1.vob for example is only 7mb.

So my question is how does one determine how titlesets map
to titles and is there any good way in megui to say import
title x.
