Sir, It's true, to transform Planer into Packed format when DirectDraw
surface supports only Packed YUV pixel format.

Here i want to copy the Planer YUV raw video data (YVU9/YV12) onto the
Planer YUV (YVU9/YV12) pixel format DirectDraw surface. DirectDraw Surface
supports Planer YUV pixel format also.

So ideally i do not require transformation of Planer YUV format into packed
YUV format.

Thanks in advance to the Discussion Group...
