    Hello,

    I am having picture quality with MPC-HC VMR 9 renderless. The picture quality drops (blocky and dropped frame rate) when I switch on VMR 9 renderless for subtitle display.

    Can the problem be overcomed, please?

  2. What frame size video are you trying to play? What video codec?

  4. A Radeon 3450 shouldn't have any problems. Try enabling the DXVA h.264 decoder in MPCHC. View -> Options -> Internal Filters -> Transform Filters -> H264/AVC (DXVA).

    It was already ticked.

    When the DirectShow video is set to System Default, the PQ is perfect.

    When the DirectShow video is set to VMR9, the frame rate dropped and the picture is occasitionally blocky.

  7. In the Custom Pres section try changing the Surface to "3D surfaces". Also try enabling "YUV mixing" and "Lock back-buffer".

    You may have a graphics card driver problem. Try updating your graphics drivers if you haven't already. Try disabling the DXVA decoders.
