DGMPGDec is an MPEG decoder suite. It is used to decode MPEG1 or MPEG2 streams from such sources as DVD VOBs, captured transport streams, *.mpg/*.m2v/*.pva files, etc. Perhaps its most common use is in decoding VOBs from DVDs.
What Do I Need to Use It?
You need the DGMPGDec package and Avisynth. First get Avisynth 2.5 (or better) and install it:
Avisynth
Download latest install package from the homepage
DGMPGDec package
Homepage: http://neuron2.net/dgmpgdec/dgmpgdec.html
Version 1.5.8 is the latest full released version. Note that binaries are no longer provided due to potential MPEGLA licensing liabilities. You'll have to build it yourself, or find binaries elsewhere. One place where the binaries can be found is: http://hank315.nl/.
You are going to use DGIndex.exe and DGDecode.dll from the DGMPGDec package, so extract them from the ZIP file and put them together in a directory.
DVD VOB file
DVD video file is with extension .vob. You are going to demux the Video and Audio stream contain in the VOB file.
I will use the Dobly Digital opening .vob which exist in many DVD as an example of this exercise.
OK. Now What?
Fire up DGIndex. Using File/Open, open your VOB. You should see the video. Now select Audio/Output Method/Demux All Tracks. That will cause your audio to be saved in a file(s) when you save the project.
Click "File" > "Save Project and Demux Video"

SmartLabs tsMuxeR – the software utility to create TS and M2TS files for IP broadcasting as well as for viewing at hardware video players (i.e., Dune HD Ultra, Sony Playstation3 and others). tsMuxeR is a part of SmartCONTENT, content preparation solution.
SmartLabs tsMuxeR is a freeware.
Download tsMuxeR_1.10.6.zip, extract and run tsMuxerGUI.exe.
Add Video and Audio to tsMuxeR
* Rename DD_Opening.demuxed.m2v to DD_Opening.m2v, otherwise, tsMuxeR cannot recognize the video, maybe it interpret the extension as .demuxed instead of .m2v
Drag and drop DD_Opening.m2v and DD_Opening T80 3_2ch 384Kbps DELAY 0ms.ac3 to tsMuxeR.
Click "Start muxing" to start muxing.
