Correct.

Sorry to resurrect an old thread but I'm really wanting to get mvc working on my pi4. I've tried the 9.2.8 version suggested but when booting the pi says the board requires newer software. Is there any way to get mvc on a pi4? Thanks

mattmarsden I guess you have to downgrade the firmware to the one, which was in use back in the days.

That on a Pi3B+ and it seems to work fine. It’s not my primary 3-D player anymore, but that might help you.

I’ve heard that the 9.8 nightly for pi4 can do hi res bitstream audio - does that version also do 3D? Thanks

No, 9.2.8 predates the Pi4, so there is no older firmware that will work. I think you'll need to use a Pi3 to run 9.2.8.

LE 9.2.8 was released explicity to support RPi4 (Generic etc. stopped at LE 9.2.6) but "support" means the image boots/runs, it does not mean "all hardware features or RPi3 work on RPi4" and the LE 9.2.8 image will only boot on the original RPi4 hardware not newer iterations that need newer RPi firmware; although that can be fixed by copying files around. IIRC, even under LE 9.2.8 the RPi4 has never supported 3D because while many RPi4 chip features are intentionally similar/same to the RPi3, the GPU is different, and OMX etc. would need work to support it, which wasn't done for release (9.2.8 shipped the same day as RPi4 was unveiled) and then never happend once things moved to GBM/V4L2 etc. .. or something like that, I forget details now, this is some time ago!
