Using IFOEdit To Dump a DVD Stream

I was using MPlayer to rip a DVD, but had a trouble dumping the third DVD title that was stored in the same VOB stream as the second DVD title. Running mplayer dvd://2 -dvd-device E:\ -vf cropdetect -identify showed the following output:

Playing dvd://2.
ID_DVD_TITLES=3
ID_DVD_TITLE_1_CHAPTERS=2
ID_DVD_TITLE_1_ANGLES=1
ID_DVD_TITLE_2_CHAPTERS=6
ID_DVD_TITLE_2_ANGLES=1
ID_DVD_TITLE_3_CHAPTERS=6
ID_DVD_TITLE_3_ANGLES=1
ID_DVD_TITLE_1_LENGTH=0.800
ID_DVD_TITLE_2_LENGTH=3196.467
ID_DVD_TITLE_3_LENGTH=3167.333

As can be seen, the longest titles are the main titles. I could dump the second DVD title with the following command:

mplayer dvd://2 -dvd-device E:\ -v -dumpstream -dumpfile title2.vob

But running mplayer dvd://3 -dvd-device E:\ -v -dumpstream -dumpfile title3.vob or mplayer dvd://3 -dvd-device E:\ crashed mplayer with the following error:

DVD Seek! lba=0xFFF08207 cell=0 packs: 0x108207-0x11AFA8

stream_seek: WARNING! Can't seek to 0xFFFFFFFF84103800 !

Core dumped ;)

I supposed this error is due to DVD copy protection. In this case, the DVD had two episodes of a show, but the episodes were stored in the same set of *.VOB files, specifically:

VTS_01_0.IFO
VTS_01_0.VOB
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB
VTS_01_4.VOB
VTS_01_5.VOB

The first episode was in VTS_01_1.VOB, VTS_01_2.VOB and the beginning part of VTS_01_3.VOB whereas the second episode was in the latter part of VTS_01_3.VOB, VTS_01_4.VOB and VTS_01_5.VOB. I tried mplayer but couldn't extract the DVD title I wanted.

So I started IfoEdit which is useful for DVD authoring and fixing. I opened VTS_01_0.IFO in IfoEdit and clicked the VOB Extras button at the bottom of IfoEdit window. Specify the destination directory and click OK.

In the next dialogs, choose the Audio track and the video stream you want to include in the output.
