\index{BluRay}
This section describes how to create a blu-ray DVD, or \textcolor{red}{BD} referring to a \textcolor{red}{B}lu-ray \textcolor{red}{D}VD, and a regular DVD, or \textcolor{red}{SD} referring to a \textcolor{red}{S}tandard \textcolor{red}{D}VD. The DVDs (plural usage of DVD means either BD or SD) created are unencrypted, unlike commercially available movie DVDs. This \CGG{} version conceivably can create different variations of DVD/Blu-ray media but for the casual user the most standard usages are readily usable and will be described here.
+In \CGG{} DVD and Bluray creation is a convenience for users who want to edit and then just make basic media without having to work too hard, therefore
+all features will not be available.
Some preliminary information follows. For NTSC, SD media is almost always $720\times480$ interlaced (the format in the United States, US). For PAL, SD media is almost always $720\times576$ interlaced (Europe, EU, and most of the world). An SD can conceivably be created with a lower resolution – for example $352\times240$ MPEG-1 -- but it is not useful. Aspect ratio for either NTSC or PAL can be $4:3$ or $16:9$.
With this mode enabled, the MPEG decoder uses a different algorithm for interlaced frames so that the
4:2:0 format chroma interlacing is preserved.

-By default, the audio when creating a DVD is always \textit{AC3}. However you can switch to \textit{PCM} (Pulse Code Modulator) with just a few additional steps as outlined below.
+By default, the audio when creating a DVD is always \textit{AC3}. However you can switch to \textit{PCM} (Pulse Code Modulator) or MP2 with just a few additional steps as outlined below.
Note that Audio must be $48Khz$ or $96Khz$, nothing else is supported, even by ffmpeg's dvd pcm encoder.
\begin{enumerate}
granted the user this privilege.
\item Make sure you have your video with audio loaded and edited to your satisfaction and you are positioned at the start of the video.
\item Use the \texttt{File} pulldown and select the \textit{DVD Render} option.
- \item In the\textit{Create DVD} window, accept the defaults or select different values and then click \texttt{OK}. Do not check "Use FFMPEG" as that will not work.
+ \item In the\textit{Create DVD} window, accept the defaults or select different values and then click \texttt{OK}. Do not check "Use FFMPEG" as that may not work.
\item When the \textit{Batch Render} window pops up, in the big box towards the bottom will be 2 lines with the first line for \textit{Video} already highlighted. Instead, click on the second line, which is for \textit{Audio}, so that it is highlighted.
- \item On the top left, you will see the \textit{File Format} set as AC3. Use the down arrow next to the box and change it to \textit{Raw PCM} by clicking on it.
- \item When you switch to Raw PCM, you see the extension in the \texttt{Output path} above change to pcm
- instead of ac3. Now just reset the extension from pcm to lpcm as that is required. In most cases if you click on the \texttt{Audio} wrench to see the settings, you will find that the standard settings of 16 bit Linear / Signed / Hi Lo work. If not, experiment for alternatives.

+on the Audio wrench and change the default Layer III to Layer II.
\item Now click on the \texttt{Start} box in the bottom left hand corner and \CGG{} will process what it can of the job and put you back at your terminal startup window.
\item You will see a few lines of output, some of which are shown below, to include the ERROR:
\begin{lstlisting}[style=sh]
/dev/shm/dvd_20240116-182336/dvd.ac3 for reading.
\end{lstlisting}
\item Change directory to the location as shown on the terminal window of \texttt{dvd.sh}.
- \item Using an editor, modify the line in dvd.sh to change \texttt{dvd.ac3} to \texttt{dvd.lpcm} and change the mplex parameter to include:
+ \item Using an editor, modify the line in dvd.sh to change \texttt{dvd.ac3} to \texttt{dvd.lpcm} or to \texttt{dvd.mp2} for mp2. In addition ONLY for Raw PCM you have to change the mplex parameter to include:
