It's that simple!!!!!!! Works great in my TL. Love Elton John's live DVD-V's from Best Buy on this.
The first part will (usually) only extract the Dobly Dirgital stream (11/12 comnpression) and not the DTS stream.
Best bet is to find a copy of DVDDecrypter somewhere and go into Stream Processing mode, extract the DTS file, and then look up a lovely little tool called "Tranzcode" and the "Tranzcode GUI".
This will take the DTS stream & demux into 6 mono 32 bit Floating Point WAV files.
Run these through your DAW and get fixed point 24/96 files.
Best of all is that DVDDecrypter will also generate an IFO file with all the chapter points in HH:MM:SS:FF or HH:MM:SS:CCC (The latter is for discWelder use) so you know where to place the markers.
Then use Cirlinca's DVD-Audio Solo.
Be aware there is a hidden "Gotcha" in DVD-Audio Solo though.
It will allow you to create a disc using 5.1 at 24/96 without MLP compression. This is out of spec, and whilst it will play on some players, because of the bitrate being a whopping 13.8Mb/sec, it is far from guaranteed to play.
You may want to consider running a Sample Rate Conversion (If the DTS stream was at 96KHz) to 48KHz.
Odds are quite high the DTS stream will be at 24/48 payload though.
