I have tried Xanim on the following and it works fine:

Amiga 3000 with EGS Spectrum board (promoting XAnim)
Amiga 3000 with Picasso II (promoting Xanim)
Amiga 4000 native
Amiga 4000 with EGS Spectrum board (promoting XAnim)

The EGS board seems to work better than the Picasso.  On our
Warped 40Mhz '040 the avi files FLY.  I must try others.

I just tested the Xanim on my A2000 with a Retina GFXBoard. It is WORKING.
