Naim CDS3 won't play 3" mini CDs. Any advice

I have the new Naim CDS3. Sounds glorious. But I have a few small, 3" CDs (they were popular for about 20 minutes in the 80s. These are irreplacable, and i had no problem playing them on the Naim CDS2 CD player, but the CDS3 just does not like them.

G+Have other CDS3 owners noticed this. Anyone have a solution?
If you have access to a PC with a CD burner then I would just copy the data to a full sized CD.
many rare promo only discs still get made and they're highly collectible......sometimes the hardware manufacturers are ironically out of touch with the music business. i'm sure they will have a b.s. excuse
