I believe (and correct me if I'm wrong) that with HDMI 1.1, the high-resolution audio formats (TrueHD, DTS-HD, etc.) will need to be decoded in the player and passed out over the HDMI connection as PCM streams to your HDMI-enabled receiver for further processing (if any). Alternatively, you can connect the up-to eight discrete analog audio outputs from the player to the up-to eight discrete analog audio inputs on your reciever, and receive the high-resolution audio that way.
With HDMI 1.3, the original non-decoded high-resolution audio format bitstream itself can be sent to your HDMI-enabled receiver where decoding can then occur (assuming support in the receiver for TrueHD, DTS-HD, etc.) as well as further processing (if any).
In other words HDMI 1.3 supports carrying the non-decoded original HD-audio bitstreams from the player to the HDMI-enabled receiver where decoding can occur. HDMI 1.1 does not allow the undecoded HD-audio bitstreams to be passed on that cable.
