How do I hook up my receiver to my PS3 player and create a surround sound. The amplifier is already connected to a dvd player which is already in surround sound but I can not do the same with the PS3.

If your receiver has another digital audio input available to connect to, such as a coaxial or optical input, you can use either of those for the PS3. Another option is to use one of the composite audio inputs, but however, your surround mode for that type of input will not be Dolby Digital, DTS or any of the high definition surround sound formats. You will instead be able to get one of the Dolby ProLogic formats, or one of the various surround modes that are proprietary to the receiver model by it's digital signal processor...depending on which you choose.
