{
bool bNeedPaint = false;
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hWnd, &ps);
if( g_mediaControl == NULL ) // we know that there is nothing loaded
{
bNeedPaint = true;
}
else
{
// If we have a movie loaded, we only need to repaint
// when the graph is stopped
OAFilterState state;
if( SUCCEEDED( g_mediaControl->GetState(0, & state ) ) )
