I've already started working towards a proper implementation of the IDirectDraw* interfaces. However that will probably have to wait until the next release cycle (also my Windows installation is currently broken and I have to fix that first). But before that I have a few questions: 1. Is someone else working on implementing any of these functions? 2. Are there any media test files that I can use for the tests? 3. What is the best way to call a method of an interface from inside a method of an interface?
