Is there no way to get more information from S3/Via? Tim Roberts told me many month ago: "S3 considers the chip specs to be proprietary. I'm under NDA." It seemed to me that he had access to the windows drivers.

That is true. But it seems, that the new engine does not support 420 planar modes. Or at least the mode is to be activated in a different way than on the old engine. The planar mode should be prefered since it transfers 25 percent less data to the slow graphics memory than the packed mode. The old engine has registers for the U and V component of the picture. The memory of the new engine at the same location seems to be not writable.
