Don't forget that all of Sony's Blu-ray releases are also crippled in
their video bit rates by the need to include space-hogging PCM 5.1
soundtracks (and that's after the PCM has been downsampled to 16-bit
resolution). HD DVD uses Dolby Digital Plus and Dolby TrueHD, which take
up a lot less space for comparable quality, and don't compromise the
video bit rate.
