Correct.

I would have expected it to mixed such that everything was 75db at the SPL meter.

According to the manual that I have for DVE, all channels are recorded at -30dB so you are getting the correct results, ie DVE is not hot...

We had this discussion in another thread regarding DISCRETE vs CINEMA DSP modes - the LFE channel in DD/DTS is boosted by 10dB above the main channels so should be 10dB louder during playback with the same source signal.

On Avia Pro (and presumably AVIA) the main channels are recorded at -20dB and the LFE is -30dB so that when you calibrate you DO expect the same level because the LFE will get a 10dB boost bringing it back up to -20dB and matching the mains.
