Drop VC-1 in favor of AVC and begin using DTS-HD Master Audio or use Dolby TrueHD with Dialog Normalization set to -31dB (the OFF setting) like Sony has been doing with their Blu-ray titles.

As I said months ago, even if DTS includes a Dialog Normalization control in their encoder (they do), because they are more quality oriented than Dolby, it would be set to OFF as the default (it's been confirmed the default is OFF). The goal of a lossless codec is to be a mirror image of the master after decompression. If the volume of the decompressed lossless soundtrack is lower than its PCM counterpart, then something is wrong. Dialog Normalization re-encodes the feed of the master soundtrack in order to use digital manipulation (digital volume control): it is therefore no longer lossless! Dolby crippled their encoder by forcing Dialog Normalization to default to -27dB (it's always ON, unless the engineer manually sets it to -31dB, which is OFF).

I hope warner will optimize their BD releases now that they aren't worried about HD DVD - Jazz Inmate 14:29:18 01/05/08 (1)
I've written to them, requesting as much. I encourage you to do the same.

  New Line released Shoot 'Em Up and the encode numbers speak for themselves. If I had to guess, I'd say that Microsoft is behind the low bitrate crap. They tweaked and tweaked VC-1 until they got the bitrate to a bare minimum (due to less bandwidth and less storage capacity than Blu-ray) so that Warner Bros would continue using VC-1 and stay with HD DVD releases. Warner Bros needs to drop the Microsoft assistance with their encodes or switch to AVC.
