Devil's Rejects Blu-ray question

No, I wasn't joking.

Hi Res audio isn't lossless.

From this very site:

DTS-HD HIGH RESOLUTION AUDIO (DTS-HD HR)
Similar to Dolby Digital Plus, DTS-HD High Resolution is an improved version of the previous DTS Digital formats. It is a lossy format that delivers up to 7.1 channels of sound with sampling frequencies from 48kHZ up to 96 kHz and 24 bit depth resolution. It runs between 1.5Mbps to 6Mbps. Note that DTS-HD HR is sometimes referred to as DTS-HD, which is misleading. Its quality is between DTS-HD Master Audio and the older DTS Digital 5.1 and DTS-ES.

This format is optional for Blu-Ray (up to a constant bit rate of 6Mbps) and HD DVD (up to a constant bit rate of 3Mbps) players. It is an alternative for DTS-HD Master Audio where disc space may not allow it. However, most studios prefer to use basic DTS Digital or Dolby Digital.
