TitleCount Property

Summary

Gets the number of titles in the disc.

Syntax

C++

public int TitleCount {get;}

Public ReadOnly Property TitleCount As Integer

public: 
property int TitleCount { 
   int get(); 
}

Property Value

A value representing the number of titles in the disc.

Remarks

Note: The ConvertCtrl.UseDVDSource and PlayCtrl.UseDVDSource properties should be set to true before specifying the DVD source image. This forces the player and the converter to use the DVDSource object when attempting to play or convert a DVD image.
