How to connect my laptop to my sorround sound and plasma tv? - pinnacle tv center serial gen

I have a Dell Inspiron 1300 with 3 USB ports (2) ports Phillips 42PF5321D plasma TV and a JVCTHC60. I bought a Pinnacle MediaCenter Best Buy, using S-video, but the custom work. All I want is the plasma in the main screen and the JVC audio system with a laptop as my main source used. Please help me to contact all together. I can not say no more use VGA.
