Robert, First, I tried resizing my video to 256x256. And it worked!!! Then I tried projecting a NPOT video, but I called setResizeNonPowerOfTwoHint(false). And that worked too!!!
I don't completely understand why the resizing was causing my movie to appear gray. Maybe because the scaleImage() call couldn't keep up with the frame rate? Anyway, thanks so much for your help! You are the man.

From include/osg/Texture: /** Sets whether to force the texture to resize images that have dimensions * that are not a power of two. If enabled, NPOT images will be resized, * whether or not NPOT textures are supported by the hardware. If disabled, * NPOT images will not be resized if supported by hardware. */ inline void setResizeNonPowerOfTwoHint(bool flag) { _resizeNonPowerOfTwoHint = flag; } This shouldn't affect the image being grey though. Also try making sure you have mip mapping off. Robert. On 7/12/07, Weitz, Andrew C. <[EMAIL PROTECTED]> wrote: > Hi Robert, > > I can see the video on the texture rectangle when I run osgMovie.
