Hi there, I recently got a Samsung LED TV and i'm using a HDMI cable to connect my PS3 to the TV. However, my Bose Home Theatre System does not support HDMI input and only supports Composite (the red and white cable) input. My TV also has a Composite audio output. The PS3 system only recognizes the HDMI for both audio and visual. If a change the setting it is only available in 2 channels. How do i setup my PS3 to work with my TV and Home Theatre in 5.1

Well its composite and there is an optical port as well. Previously when i connected my PS3 using composite to my CRT and Bose at the same time. It ran 5.1. But not now
