I judt got my Yamaha 370 and have a few questions about optimum sound. I currently have the PS3 connected to my TV via HDMI but have the optical audio going from the PS3 straight to my Yamaha. Is the best way to get sound from my system? I have read alot of good reviews about PCM audio, but dont know anything about it or how to get it through my system. Also as far as my cable box goes, should i connect the audio the same way as the PS3? The sound on my new TV isnt very good, so i think it would sound alot better going straight to the receiver. The TV is a Samsung HLS5687W

Thanks for the help and any info
