    1080p mkv file problem (MC and MPC-HC)


    hi,

    1. Windows Media Center(x64) plays 720p mkv files fine(no dxva though). but 1080p files give choppy playback(not watchable at all). How to fix 1080p playback?

    2. 720p mkv uses dxva in Media Player Classic-HC(x64), 1080p doesn't. anyway to force dxva?

    I have haali media splitter 1.9.63.13 and MPC-HC 1.2.1164(x64)

    please help.

    Is the 1080 file you have DXVA compliant?

    I think so, because in Windows XP it used DXVA.

    I would make sure, use Gspot or something equivalent to that and see if the profile is 4.1 or lower.

    Gspot doesn't show anything for both 720p and 1080p.

    Unless things have changed and they often do, you shouldn't be getting DXVA on either of those. There are other factors to consider as well for compliance such as ref frames etc. I would of thought your processor would be capable of either files but you could try CoreAvc it is a very efficient codec and can use Cuda for Acceleration as well. Other than that the only thing i can suggest is to ask on Avsforum or Doom9.

    i say get coreavc and don't bother with dxva. my processor isn't great either but i run 1080p with no problems just using haali + coreavc in mpc-hc.
