This month's first batch of HD reviews at Secrets had nine Blu-ray discs, only two of which had uncompressed PCM tracks. Of the other seven, four had DTS-HD (only one of which with Master Audio), one had DTS-ES, and two had only plain old Dolby Digital. Those two PCM tracks seemed to be the preferred, although of course nobody can actually hear the DTS-HD Master Audio track to know how it might stack up to the PCM. Better or not, PCM still seems to be slowly scaling back on Blu-ray.
