Yup these are DVDs so for sure you will need a DVD burner. Also, these are Dual Layer DVDs, so you will need one that has that functionality.

The first thing i did was copy mine. The disk are also not copy protected so you dont have to decode them to copy them, just copy with your dvd writing software to DL disk.
