Well the info. in my post describes how to demultiplex (extract) all the
video, audio, and subtitle streams in a VOB file set using VobEdit. Once
you've done that you can multiplex (combine) the video and one (or more)
audio streams back into a single MPG file. There are many tools available
to do this, see a list of Video De/Multiplexers here:
http://www.videohelp.com/tools?s=111#111
I used ImagoMPEG-Muxer (6th down in the list) the other day, it's free and
worked perfectly.

>>Hi John,

>>The info. about renaming the files as mpg is not a good way to do this.

>>Here is what you should do.
>>
>>1. Copy all the files from the DVD onto your hard disk (make a new folder
>>for them). NOTE If your DVD has been copyright protected use DVD Decrypter
>>to copy the files to your hard disk, info. on DVD Decrypter can be found
>>here: http://www.videohelp.com/tools?tool=DVD_Decrypter
>>
>>2. While they're copying (it will take a while) download VobEdit 0.6 from
>>here:
>>
>>http://www.videohelp.com/download/Vobedit06.zip
>>Homepage: http://www.ifoedit.com/
>>
>>It is free software and requires no installation, just extract vobedit.exe
>>from the zip and run it.
>>
>>READ 3. CAREFULLY.
>>
>>3. When a DVD is compiled all the video and audio and subtitles are
>>combined together (called multiplexing) into sequences of VOB files, a VOB
>>file has a max size of 1GB which is why you get a sequence. Each VOB file
>>will usually contain a MPEG2 video stream, one or more audio streams, and,
>>if appropriate, one or more subtitle streams. VobEdit will allow you to
>>extract these streams into separate files (video, audio, etc).
>>
>>A DVD can have multiple 'tracks' on it (nothing to do with an audio track,
>>just a term used for a specific sequence of VOB files on a DVD). So your
>>DVD may have VOB files named something like this:
>>
>>VTS_01_1.VOB -- track 1, first in sequence
>>VTS_01_2.VOB -- track 1, second in sequence
>>VTS_01_3.VOB -- track 1, third in sequence
>>VTS_02_1.VOB -- track 2, first in sequence
>>VTS_02_2.VOB -- track 2, second in sequence
>>VTS_03_1.VOB -- track 3, first in sequence
>>VTS_03_2.VOB -- track 3, second in sequence
>>
>>The first number of a VOB file sequence is the DVD track number, the
>>second number specifies the ordering.
>>
>>Since yours is a music DVD (IE. not as long as a movie) each DVD track may
>>have only one VOB file, so you may have VTS_01_1.VOB, VTS_02_1.VOB,
>>VTS_03_1.VOB or everything on the DVD may be contained in just one DVD
>>track; VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, VTS_01_4.VOB,
>>VTS_01_5.VOB. It depends on how the person who made the DVD structured it.
>>
>>4. You are only after the data of one of the songs but which DVD track is
>>it on? To find out load the first VOB file of each VOB sequence into VLC
>>and see if it's the correct video. EG. Try VTS_01_1.VOB then VTS_02_1.VOB
>>etc. If the correct video is in VTS_02_1.VOB then you know you're after
>>the second DVD track. If your DVD only has one track you'll just have to
>>extract it all and later on find where the song's video starts and stops
>>in the one long video file of all the video on the DVD.
>>
>>5. Extracting the separate files (video, audio, etc) from the VOB files is
>>called demultiplexing. Run vobedit.exe and click 'open' in the bottom left
>>corner, then navigate to the folder that has your DVD's VOB files. If you
>>established which track has your video in it open the first VOB file of
>>that sequence of VOB files. EG. VTS_02_1.VOB if you only have one DVD
>>track on the DVD just open VTS_01_1.VOB. NOTE you will NOT need to open
>>further VOB files in the sequence, just the first, VobEdit will
>>automatically move through the sequence of VOBs. So if you open
>>VTS_02_1.VOB it will know to do VTS_02_2.VOB and VTS_02_3.VOB as well if
>>they exist.
>>
>>6. When you open the VOB file a whole load of info. will be displayed in
>>VobEdit. Now click on 'demux' also near the bottom left corner and a
>>dialog will pop up. All the boxes will be unticked, now JUST tick 'demux
>>all video streams', 'demux all audio streams' and 'demux all subp
>>[subtitle] streams' (DO NOT TICK ANYTHING ELSE) and click 'OK'. A 'save
>>as' dialog will pop up, so just choose a new folder to save the
>>demultiplxed files into and the demultiplxing will start (it will take a
>>while to finish).
>>
>>7. The folder you just chose will now have a .m2v file which is MPEG2
>>video, a .ac3 dolby stereo file (or a different extension depending what
>>audio format is on the DVD) and .sup files if there are subtitles on the
>>DVD. [There may be more than one audio file if there are more than one in
>>the VOBs --not likely on a music DVD].
>>
>>8. The .m2v file can be opened by any video playing software, so have a
>>look at it and see if you've got the right video. Note that VLC often does
>>not display the correct time info. for a video file. BS Player has a free
>>version which is pretty good, see here: http://www.bsplayer.org/
>>
>>That's it -- good luck !!
>>
>>Hope this helps,
