    Hi @joecrow

    Same crash :)

    Application: MediaPortal.exe
    Framework Version: v4.0.30319
    Description: The process was terminated due to an unhandled exception.
    Exception Info: System.NullReferenceException
       at Microsoft.DirectX.Direct3D.Surface.Dispose()
       at Microsoft.DirectX.Direct3D.Surface.Finalize()
    So madVR crash windows happen when the above crash is trigger.

    Will try a bin for you to see how it goes :p

    Attached is to test :)

    It seems that on togglescreen, the D3D is kind of reset for the backbuffer etc. and after a while, code need to free/dispose memory to something already disposed or something else and then lead to the crash. I think it's related to GC (Garbage collector).

    Can you try also to reproduce with EVR ?

    Seb I think my main problem was with the latest NVIDIA. I have gone back a version and have yet to see any issues at all (touch wood) even with v430 (either checkbox option). Sorry if I sent your efforts in the wrong direction!

    I'll continue to monitor and update when you make new versions as regression testing :)

    FCU on DRR on AVR off. I try to start the video, but the screen stayed black. It was weird, because the madvr information looked like the video was running. MP crashed completly and I had to shot it up.
    FCU on DRR on and also AVR on. First start of the video failed. The GUI jumped back to where I can start the video, but no crash. After that, the starts of the mkv ran smoothly.
    FCU off DRR on AVR off. worked perfectly

    Hi Sebastiii
    I have tried the new core and had a Madvr crash both with Auto3D on and off. With EVR I had a single incident where the video froze, with audio still playing and on manual stop audio stopped but then no more control and I had to use the task manager to close MP. After restarting I have not yet had any further problems with EVR despite a long period of heavy usage.:rolleyes: Logs and crash reports attached, names say all.;)
