I have a Blu-ray that eac3to (and other tools) reports as being 1080p24 (not 1080p24/1.001).

M2TS, 1 video track, 2 audio tracks, 4 subtitle tracks, 2:18:32, 24p
1: Chapters, 41 chapters
2: h264/AVC, 1080p24 (16:9)
...
v02 The video framerate is correct, but rather unusual.

I didn't even know that 1080p24 (non drop frame) was even a valid BD format. Does a Blu-ray player actually play it back at 1080p24 or just slow it down slightly to 1080p24/1.001?

1080p24 and 720p24 are fully blu-ray compliant. Quite a few Blu-ray disc exist these days which use this framerate for film content, abandoning the legacy 23.976 fps from analog TV times.
AFAIK Blu-ray players won't slow it down to 23.976.

So a Blu-ray player is capable of changing its output framerate to either 24.000 or 24/1.001 or they just have a glitch in the video every 40-something seconds? I seem to remember a criticism of one of the early Samsung players was that it output 24.000 not 24/1.001 and it did have a regular glitch as a result.

They play it just fine at 24 fps without glitches.
