I think you just made my night. I guess I never saw your previous topic: Building a game console card host machine, looking for CD-I ISA board.
Regarding the CD-I/PC 2.0 card:
Philips 22ER9170/00 seems to have been the CD-I/PC 2.0 part number for the PAL version and 22ER9170/17 for the NTSC version, incidentally. It's mentioned on the reverse side of the CD-I/PC 2.0 flyer but I haven't seen that in print on the Internet yet really aside from Philips' website. So, another VOGONS first? 😉
I found a crap website that claimed to have the user manual but it seems it was just a scam, probably trying to infect you with viruses. Might be worth pestering Philips since it is listed on their website, though I am sure we can all guess what the response to "can you send me any information on the CD-I/PC 2.0 card, any of its drivers or manuals, and I'd even buy one if available" will be: https://www.philips.co.uk/c-p/22ER9170_00/-/support
http://www.theworldofcdi.com was also looking for the CD-I/PC 2.0 card in 2017. I doubt they found it, but they responded to that thread again in 2019 to say that they got their hands ons tons of authoring software options. They also acquired the I2M PCI card (though they do not mention it in the AssemblerGames post)

This seems to be a little more info on the card, though I wonder if it wasn't the possible "CD-i/PC 1.0 card" instead, as all these articles suggest a minimum CPU of a 386, while the flyer on the CD-I/PC 2.0 card claims that it requires a 486:

Unfortunately I cannot tell you about the Creative DXR2 DVD Decoder. If I had to guess, it probably only supported "CD-i Movies" and not "CD-i Games".
I scanned a C-Cube CL450 developer manual once, it's here in case it is at all useful, but I guess it isn't: http://mess.redump.net/datasheets/c-cube
