How is your PS3 connected to your receiver? If it is by HDMI the proper boxes should be checked automatically. If it is by optical cable, you'll have to do it yourself. Many non-HDMI receivers don't support anything higher than 96 kHz, so you may want to leave the 192s unchecked. The majority of the HDMI receivers do support 192 on input (many of those downsample it to 96 after receiving it though). But as I said, HDMI should auto-detect what is supported, and you should leave it there.
