    So i just built a new rig with an Intel 4770S with Intel HD graphics on a Asus Sabertooth Z87 running MP1.4 preview on win8. And whenever DRR is enabled, and i try to watch tv or a movie, i just get booted back to the menu or a popup saying "unable to play (video/audio codecs or livets). The refresh rate does change though. A log is attached where i first try to watch tv (50hz), and then try to watch a movie (24hz), default refreshrate is set to 60hz.

    So i would suggest to check your Videocard drivers & Audio Renderer settings (and see if you can play the movie in windows)

    I can. And playback of all types of content in mediaportal works perfectly when DRR is switched off... But i did have to set the audio render manually to the one of my reciever (NR-808) before that even worked, so maybe you're on to something

    Also i can report that TV playback works if i start mediaportal in 50hz, and movie playback works if i start mediaportal in 24hz mode...

    Oh, and i just switched back to my old Geforce 520. And now it works. So obviously the Intel HD 4600 dosen't like MP or the other way around (and i also the black levels are awful on the Intel... more grey than black). I also tried all (both!) versions of drivers for the Intel...

    I would suggest you try an external refresh rate changer with DDR, enter the command / path to .bat in the action field
    you could try "12noon"[DOUBLEPOST=1370468604][/DOUBLEPOST]to solve the black problem you need to make sure that both the video codec, the video card settings and the display are all set to use the same black levels (16-235 vs 0-255), If one of them is set to different output then it causes you to either have grey blacks or loss of defnition/contrast in very dark scenes.

    The 12noon solution seems to overcomplicate things... And will it switch according to content type considering it is an external application?
    Also, considering it works with the nvidia card, i guess you will see more people giving bug reports on this soon on the hd4600 (considering the haswell chips just hit the market this monday ;) )

    Thanks for the tip with the levels... I thought it was enough to just set it in the gfx settings (which i set to 0-255), i will try that once i bother to pull out the nvidia card ;)

    yes intead of running the internal refresh rate changer it will run the external application to change the refresh rate, setup very simple, when watching movies you wont notice any difference. If this solves the problem then we know it is the internal refresh rate changer that is the problem and you can post a bug report.

    Check that screen resolution remains same after refresh rate changes . This problem is not uncommon[DOUBLEPOST=1370524596][/DOUBLEPOST]Also setup a delay of half second after refresh rate change. This is also sometimes needed
