I ripped an exercise DVD I own (21 Day Fix) so I could watch it from my Mac. I ripped it as an .iso disc image. It's 8 GB, which is normal. I decided I wanted to convert each routine to an MP4 file and import them into iTunes so I can stream them to my Apple TV. When I open the .iso disc image to copy out the VIDEO_TS folder, the VIDEO_TS folder is 82 GB. It's filled with a whole bunch of 1.08 GB files. How is it possible for the VIDEO_TS folder to be over 10 times the size of the .iso file that contains it?
