A typical DVD Audio disk has an output of 88.2kHz or 96kHz in a format called PPCM or "Packed" Pulse Code Modulation.
The 88.2kHz and 96kHz stereo tracks on typical DVD-Audio discs are not packed. Meridian Lossless Packing is only applied to the high resolution multi-channel tracks. The reason for the packing is to allow 5.1 channels of hi-res data to fit into DVD's maximum throughput rate of 9MB/sec; this is unnecessary for the stereo tracks as the bandwidth can easily accomodate 2 channels of 96/24 data.
...my DVD player does not output high resolution PCM in more than Stereo
The digital outputs on your RP-91 or any other DVD player can handle 2 channels of 96/24 data; this is within the S/PDIF spec. Even my five years old Pioneer DV-525 player outputs a clean 96/24 signal via the digital outs, with no downsampling. More channels of hi-res audio, even when packed, won't fit through the digital outs of standard players. So your RP-91 is not alone when it comes to this limitation.
