Pinguy Builder available for this purpose. Pinguy Builder developed from Remastersys source code. So Pinguy Builder is very easy to use tool for live dvd creation.
I tried to build Live DVD from Ubuntu MATE Linux. MATE Desktop available with this Ubuntu distro. MATE desktop gives classic look, not like Unity.
2. Download Pinguy Builder package. Choose appropriate version. Read the instructions in the download page first. Pinguy Builder Version 4 works with Ubuntu 16.04 and select version 3 for Ubuntu 14.04.
3. Install Pinguy Builder.
Open terminal and install the package.
dpkg -i pinguybuilder*
The package required dependancy files. The command execution will end with error messages. Try to install dependency files,
apt-get install -f
Pinguy Builder can find in System > Administration after installation.
4. Prepare system for Live DVD creation (Add and remove applications).
5. Build Live DVD using backup/Dist option.
