Surround sound for gaming, or just movies (DVD/BD) ?
I don't know if PS3 does DDLive (I don't own one) but if it doesn't then the only way to get surround sound in games is through HDMI.
Converting DD5.1 optical to stereo analog you will lose the true surround and only have two channels. The converter boxes might have something that converts the signal to a PLII decodable signal that would kinda preserve the surround channels.
