A DVD-A can be 48kHz/16-Bit or even 44.1kHz/16-Bit. My players sometimes show LPCM for a DVD-A. I think LPCM is just not compressed using MLP, it is lossless. I think either MLP or lossless uncompressed LPCM can be used on a DVD-A. Most use MLP for space requirements. I don't have this DVD-A and can't check it.

The way it works is like this.
DVD-A resolutions in surround go from 16-44.1 to 24-96.
DVD-A resolutions in stereo go from 16-44.1 to 24-192
MLP usage is determined by 2 factors:
1 - Do I need the space reduction that MLP will give me?
2 - What is my data rate?
MLP will give - approximately - a 50% reduction from the original, depending on the mix and it's complexity. It's impossible to say as it is a VBR stream, not a CBR stream.
Also - and this is the cruncher - you have a data rate maximum of 9.6Mbits/second. 9,600 kbps is your limit.
24/96 5.1 or 24/88.2 5.1 both exceed this, so the use of MLP is mandatory for those streams. 24/96 4.1 will also - usually - exceed the data rate limitation. It's a borderline one, like 4.0 at 24/96 - sometimes some apps will allow this, other times not. When in doubt, use MLP -
the output is bit-for-bit identical to the input. There is no degradation.
PPCM = Packed PCM, and is the same as MLP. Just a different acronym for the same thing.
LPCM = Linear PCM, and is what we all know of as PCM WAV or AIFF files.
