Things You'll Need
Instructions
Download the software GYP Player online. Several versions are available online for PCs and Macs. Install the software following the prompts after double-clicking the setup file.
Download a CD burning software such as Nero Burning ROM or Roxio. This software will allow you to transfer the GYP Player software to a CD-R.
Open the zip file of the GYP Player software using WinZip. Open WinZip, navigate to where the GYP Player software is on your computer, then select the .zip file and click "Extract." Select an empty directory on your computer for the file to save to. In the same directory, save the .mpg, .mpeg or .avi video files you'd like to play on your Dreamcast.
Use the CD-burning software you've downloaded to burn the contents of the directory to the recordable CD. Follow the prompts of the software to complete the process. When it's completed, insert the CD into the Dreamcast, and turn on the console. Your video files will appear for selection after the console has finished booting.
