I have a feeling this would get a faster reply on a DX message board rather than a java one as the bug seems to be with DX9 rather than with java.

If applicable you could have the game loop through the tiles at the frame rate required, or with the other animation method you presumably have to tell it to advance, and call an advance frame method before the draw method. You would have to add an advance method to your tile class(empty) and create a animated tile that would override the advance method. If this doesn't work with your architecture or you don't understand feel free to e-mail me at satinyou@googlemail.com
Hope this helps
