Rotation Support for omap850

Hi all ,
I m trying to rotate image by 90,180,270
on omap850 board.
For 180 it works fine , but for 90 & 270 it doesnt work .The image seems to be splitted for 90 & 270.
Does anyone tried rotation for 90,270 for
the omap850 ?
Omap850 uses dma to transfer the video content.
please update me on this. Thanks in advance
