Since this is a Meridian forum, I will talk a bit about the TrueHD on the disc. First, I encoded all audio and video with the exception of the audio on the TrueHD trailer and the audio and video on the DTS-HD MA trailers.

The montage is available with PCM, TrueHD and DTS-HD MA audio. I encoded TrueHD with DialNorm set to -31 instead of -27. This results in matched levels between all three. I believe it to be the first apples-to-apples comparison. The audio is 16/48. I had 24/48, but I could not mux because I used all the available video bitrate. My goal was to get the video bitrate as high as possible. The PS3 will show peaks as high as 50 Mbps for video thanks to the VBV buffer.

If you add up the file size of the TrueHD + the DD 640kb, it is still smaller than the the DTS-HD MA. Note that I did us the 1.5 Mbps core for DTS. I would have offered a high bitrate DD if it were allowed.
