In addition to the basic settings that are always displayed on the screen for importing files, you can configure certain additional settings with the Recode an Entire DVD to DVD task.     
The following buttons are available: 
Disable
Removes video titles on the original DVD from your compilation.  
This way, you can disable, e.g. unnecessary extras, and create more space on the target DVD. Disabled files are not transferred to the copy during the burn process.
This button is only enabled if at least one DVD video title has been imported into the content area and selected there.
Activate
Enables video titles that were previously disabled. The files that are added again are transferred to the target DVD when the compilation is written.  
This button is only enabled if at least one DVD video title has been disabled in the content area and selected there.
Lock Ratio
Locks the automatic change of recoding quality for a DVD-Video title. It is still possible to make manual changes to the quality settings by moving the slider.  
It could be a good idea to lock individual video titles if you want to improve the quality of other content (and therefore, the quality of the remaining content is lowered proportionately). A locked title is protected from the proportional adjustment in this case.
This button is only enabled if at least one DVD video title has been imported into the content area and selected there.
Unlock Ratio
Unlocks automatic recoding quality changes for a video title.  
This button is only enabled if at least one DVD video title has been locked in the content area and selected there.
