Just purchased a Samsung 8500 lcd and a PS3 for bluray. I have an HDMI to the tv and since my receiver isnt HDMI, I am using the optical line from the PS3 to my receiver.- While playing a blu-ray movie I noticed a hint of lip syncing,(enough for my wife to notice), but in other parts it corrects then continues again. What could be the culprit? Better HDMI cable, the video processing options for the tv/blu-ray player making it out of sync (I'm running it 24hz)- any audio options in the blu-ray player to adjust?
