Basically I installed a new OS so I have to do everything from scratch. I downloaded CCCP with MPC-HC, and I also have CoreAVC 2.6. I'm trying to run a 1080p MKV video, and it lags. I'm not sure whether it has something to do with the video, audio or subtitles. All I know is that it works on my laptop (the karaoke doesn't work on the laptop, but everything else is fine no video lag) so I'm sure this computer can run it. It just has to do with settings and codecs and all that fun stuff. I'll attach an insurgent log. Thanks in advance.
