I have a DVD player that can play files on a USB key.
It also works with a cable to my MP3 player (4gb chipod)

But it doesn't recognize any external USB hardrive. Even one <32Gb, fat32, single partition, everything I can think of to make it look simple.

Any ideas?

USB Mass Storage devices provide the device to which they are connected with their mass storage class which is defined in a specifcation. As a result, the DVD player can differentiate between a flash drive and a USB hard disk drive, regardless of its size.
