How can i use disc on computer

First off, you need to have a DVD R/W drive in order to use the disc in the picture. If you don't have one, you can purchase an external drive and install it onto your system. From that point, using the disc on your computer I take it to mean how can you BURN a DVD? This depends on your operating system and what program you use to burn it with. There are too many to list here, I suggest using a search engine and asking how to burn DVD's with my ??? system.
