dvd_TitleFrameCount
TitleNumber: number of the title requested (in the 1..n range) or 0 for the global information (dvd_TotalDuration and dvd_NumberOfTitles)

double TotalDuration = Videograbber.DvdInfo ("e:dvd_TotalDuration, 0)
- the number of titles in the DVD:
int NumberOfTitles = (int) Videograbber.DvdInfo ("e:dvd_NumberOfTitles, 0)
- the duration of the 1st title:
double TitleDuration = Videograbber.DvdInfo ("e:dvd_TitleDuration, 1)
- the number of frames of the 1st title:
int TitleFrameCount = (int) Videograbber.DvdInfo ("e:dvd_TitleFrameCount, 1)
- the frame rate of the 1st title:
int TitleFrameRate = (int) Videograbber.DvdInfo ("e:dvd_TitleFrameRate, 1)
- the width of the video resolution of the 1st title:
int TitleVideoWidth = (int) Videograbber.DvdInfo ("e:dvd_SourceResolutionX, 1)
