HI Brian, Create a subclass from osg::ImageStream as pre the video plugins (src/osgPlugins/xine and src/osgPlugins/quicktime), this will provide general controls as well as support for automatic use of PBO's for texture downloads. Alternatively you could do the PBO setting yourself.
Also use TextureRectangle to avoid any resizing to a power of two. Or use non power of two textures. Robert.
