I have used Smartripper and DVD Audio Ripper to demux the LPCM 2.0 48kHz 24Bit Audio from my new Dave Matthews Central Park DVD. Each wav file I have created is full of static and very slow. I can hear the concert underneath a fairly loud hiss, and the concert sounds like it is at half speed. Any thoughts of what is going on. I have searched the forums and cannot find anything specific to lpcm that is a reason for this.
Answering my own question. Hopefully this will help others here in the forum.
When you buy a concert DVD, there is usually a corresponding audio CD of the same material. This is the case with the DVD I spoke of. I would like to listen to the music in the car as well as play the DVD at home. I mean I do own the DVD. Why purchase the CD when I already own the digital bits on the DVD!!
This topic blurs the boundry of dvd ripping and audio encoding. Since I started the thread here, I will finish it. If moderators wish to move it, that is cool.
Anyway, ripping the vobs and ifo to hd with SmartRipper or DVD Decrypter was the easy part. I was able to Demux the LPCM 48000/24bit audio to a wave that is not playable in all of my editors.
I found this snipet with a program called LPCM24. This nails it exactly. Here is a paste of the readme file. You can download this awesome program at http://rarewares.hydrogenaudio.org/
The best way to obtain 24bit WAV files from DVDs using lpcm24
1. - Rip your DVD with your favourite ripping tool (DVDdecrypter,
SmartRipper, etc.)
2. - Run vStrip (VOB ripping utility)
***Don't use VobEdit! It somehow ruins the stream.
3. - At the first tab (Input) <Add...> the VOBs you ripped in
sequence.
4. - At the second tab (Ifo) load the IFO file for that DVD
5. - At the third tab (Output)
- select output name, saving it as "Raw PCM stream" file type
- at the "Streams" section, click <None>, then select the
SubStreams box
- select the code for the LPCM stream (usually 0xA0)
- at the "Output Options", select the "Demux" box, and make
sure nothing else is selected
- click <Run>
6. - After the LPCM stream has been demuxed, open the command prompt
and go to the folder where you saved it. Run lpcm24. After
it's finished processing, you'll have a standard 24bit WAV file
that you can open on Winamp, CoolEdit, etc.
-48 :To write the WAV header as 48kHz. The default setting is 96kHz
-ex :To write a WAVE_FORMAT_EX header. Used on Win2000/XP. Less compatible
than the default header, but some programs might require it.
Enjoy!

Thanks goes out to rjamorim for the readme and thomaspf for the awewsome program.
I tried this, and managed to get a wav file, but my cd burning software will not burn it to cd audio. Also I want to split the large file into separate files for each song. Any thoughts?
If I remember correctly, you need a program to convert the 24 bit audio to 16 bit. I think the CD standard will only allow 16 bit songs, so a cd burning program will not let you make an audio cd for these files. You can use a digital audio editor to down sample the files to 16 bit and then use it to chop up the massive wav into track sized wavs.
