comment Pixel Shader, YUV-RGB Conversion failing
Yeah. Multiplied with 256. Still looking for a better way to debug Shaders in Visual Studio ;) I would have seen this immediately.

Did and that actually worked ;) The conversion is out of my hand in this case - the format is fixed and the image is life and the decoder can not do additional transpositions. The layers also have different sized (U and V are quarter images, half width and height). Please add as answer and I will approve ;)

comment Rendering a Sprite with an Effect… how?
Yes, that was it. ITdoes not "WORK" (as - does what it is intended) but at least now the image changes when I comment out the effect or not, which was not the case before when it was a non-operation. And this alone was the question - how to get a sprite to USE the effect. Thanks ;)

Well, it WORKS - it does not do anything with the shader, but it works. Both textures are the same size - so the sprite mechanism is doing all the stuff correct ;)
