When you setup your wireless network it's called a homegroup and once setup ou will have the devices thast are in the homegroup listed and when you look at the network on your computer you will see all those devices wheter it's computer , blue ray player or cell phone. Once the blue ray player is connected you can have the laptop turned on and the music of video files that you want to share will have to be in a folder that has been designated as being shared. Then in the blue ray player's menu you will see the laptop and be able to access that folder.
