The optical out is only giving you standard def dolby and the like, no different than a regular dvd player. If you were to buy a new player that decoded and sent out the signal on analog out to the inouts on the H/K then you would get the new formats or buy a new avr which does the decoding and hook the PS3 upto it via HDMI.

I am rushing did that make sense?
