That is a misprint on the DVD-Audio cover. The stereo on the old DVD-Audio is actually 24/96 (at least on my copy).
Interesting. I'll have to check that out.
update: Yep, both titles are 24/96 PPCM. Maybe there is a low resolution PCM track that only shows up on non-dvd-audio players.
One other thing I noticed is that one of my disks is made in the USA. How odd. I remember them both being made in the EU and I had bought them both at the same time from overseas, so maybe one got lost. Will need to do some looking around for it.
