We can drop the custom table. For some reason, the interop does not accept GL_RGB_RAW_422_APPLE as internal format for GL_RGB_422_APPLE, so switch the format table to use GL_RGB (this way both interop and real textures work the same). Another victim of the apparent requirement of exactly matching texture formats is kCVPixelFormatType_32BGRA. vo_opengl wants to handle this as normal RGBA texture, with a swizzle applied in the shader. CGLTexImageIOSurface2D() rejects this, because it wants the exact internal format. Just drop the format, because it's useless anyway. (Maybe this is a bit too fragile...)
