I think that everyone is forgetting that with blu-ray it is better to let the player decode the audio as pcm and send it to the receiver if you have any interest in PIP or Web-enabled supplements. If it is sent bitstream then it is not possible to have the audio tracks mixed due to hdmi handshaking. At best your audio will just be downconverted from lossless to lossy and at worst you may not get any audio at all from this additional content. I hope my memory is correct from the article that I read back in February about this.
