Things You'll Need
Instructions
Purchase a Sony PlayStation 3 IR adapter. This small device allows devices such as universal remote controls to communicate with your PS3. In turn, you can use a universal remote to control your PS3 while watching a DVD or Blu-ray disc.
Plug the base of your IR adapter into a controller port on the front of your Sony PlayStation 3.
Program your universal remote control using the IR code indicated in the user manual of the specific model of IR adapter that you purchased. This code is how the remote is able to identify and communicate with the adapter, which then passes the instructions along to the PS3. The specific steps of how to program your remote will be different depending on which remote you've chosen, so see the instruction manual that came with it for more specifics.
