I am copying a 4.7 GB dvd contents into my local drive but the total size of DVD is being shown as 415 GB!. How is that possible? Because of which it is showing less space (as my drive is of 150 GB) and thus cannot be copied?

I am surprised that how a 4.7 GB dvd contains 415 GB data? Its a movie DVD (contains dual subtitles and dual language, if that helps)

Attached is the image for reference

Inside the DVD the video folder shows 415 GB
