macOS C++ Problem displaying a movie with firefox under Vista

[mdemarco]

I am using the quick time api within an activex atl component that gets loaded into the browser. Under XP it plays the movie fine. Under Vista I can't see the movie at all and all I hear is audio. I downloaded the latest Vista service pack but still the same problem. Any insights? I have provided some code below.

bool CPlaybackWindow::OpenMovie( char *pszMovieFile )
{
	bool	bStatus = false;
	FSSpec	stFSSpec;
	short	nMovieRefNum = 0;
	Rect	rMovieControllerRect;
	RECT	rWindowRect;
	char	szMovieFile[MAX_PATH];

	gPercentInFromEnd=0.0;

	ZeroMemory( szMovieFile, sizeof( szMovieFile ) );

	SetGWorld( (CGrafPtr)GetNativeWindowPort( m_hWnd ), NULL );

	strcpy( szMovieFile, pszMovieFile );
	c2pstr( szMovieFile );

	if( FSMakeFSSpec( 0, 0, (unsigned char *)szMovieFile, &stFSSpec ) == noErr )
	{
		if( OpenMovieFile( &stFSSpec, &nMovieRefNum, fsRdPerm ) == noErr )
		{
			if( NewMovieFromFile( &m_stMovie, nMovieRefNum, NULL, NULL, newMovieActive, NULL ) == noErr )
			{				
				GetWindowRect( &rWindowRect );

				//mdm
				rMovieControllerRect.top	= rMovieControllerRect.left = 0;
				rMovieControllerRect.bottom	= (short)rWindowRect.bottom - (short)rWindowRect.top;
				rMovieControllerRect.right	= (short)rWindowRect.right - (short)rWindowRect.left;

				//rMovieControllerRect.top	= 368;
				//rMovieControllerRect.left = 225;
				//rMovieControllerRect.bottom	= (short)rWindowRect.bottom - (short)rWindowRect.top + 362;
				//rMovieControllerRect.right	= (short)rWindowRect.right - (short)rWindowRect.left +225;

				if( ( m_stMovieController = NewMovieController( m_stMovie, &rMovieControllerRect, mcNotVisible | mcScaleMovieToFit | mcTopLeftMovie ) ) != NULL )
				{
					SetMovieSelection( m_stMovie, 0, GetMovieDuration( m_stMovie ) );

					MCEnableEditing( m_stMovieController, true );

					MCSetActionFilterWithRefCon( m_stMovieController, MCActionFilterProc, (long)this );

					bStatus = true;
				}
			}

			CloseMovieFile( nMovieRefNum );
		}
	}

	return bStatus;
}

Last time I did anything with the QuickTime's C API I had to call MoviesTask() periodically to play the movie properly. Not sure if that still applies here but it's worth a try.
