In addition to the basic settings that are always displayed on the screen for importing files, you can configure certain other settings with the Compile a DVD task.   
The following buttons are available:  
Delete
Deletes imported video titles from your compilation.  
This button is only enabled if at least one DVD video title has been imported into 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. 
Trim Movie
Opens the Trim Movie window, where the selected video title can be trimmed. 
This button is only enabled if at least one DVD video title has been imported into the content area and selected there.
Merge Titles
Merges selected video titles and pastes them to a common folder, Merged Titles. You can rename the folder according to your own preferences.  
This button is enabled only if at least two DVD video titles have been imported into the content area and selected there.
Split
Splits merged video titles.  
This button is enabled only if at least two DVD video titles have been merged into one.
Default Streams
Opens the window Default Streams in which the streams for audio and subtitles can be selected. 
This button is only enabled if at least one DVD video title has been imported into the content area and selected there.
