On the unit's original firmware, I seem to be having a potential problem/bug/poor design with the DSP auto presets.
Basically, for Blu-ray I will be sending the unit 5.1-7.1ch PCM that has been decoded in the Blu-ray player, and I want the unit to apply DPLIIx + DSX processing to it (9.1ch). However, it seems certain PCM multich formats trip this up such as PCM 7.1 and with these formats it appears this mode is not available, only DSX alone... Which is fine since the back channels are present in the stream, but instead of defaulting to DSX (9.1) it defaults to multich (7.1) which doesn't make sense given the preset I requested was a 9.1 preset. Anyone else run into this? My thoughts are if DPLIIx + DSX 9.1 mode is not available when fed a 7.1 stream, the processor should default to DSX 9.1 and not PCM 7.1. Thanks.
