Elgato Game Capture HD60 Pro can't capture HDCP content. The PS3 outputs video via HDMI that is protected via HDCP at all times.
Elgato Game Capture HD60 Pro only accepts unencrypted HDMI input that doesn't protect the signal via HDCP.
That means that Elgato Game Capture HD60 Pro cannot capture any video from the PS3 over HDMI.
To capture PS3 gameplay, you can use the original Elgato Game Capture HD hardware, along with a special PS3 cable that comes with that unit. That older Elgato Game Capture HD unit captures a Component/D-Terminal signal from the PS3 that is analog, and therefore not protected via HDCP.
More information about HDCP can be found here.
