I believe there are some standard DVD player that can do DivX Ultra at 1080p. One for example:
Philips DVP5982/37

If you're looking at Blu-ray player with DivX, you will have to wait for Panasonic. Their press release announced that they will release DivX certified Blu-ray player (but only in Europe and Russia at the moment.)

Alternatively, PS3 can do Divx.
