I'm facing a problem with Blu-ray (.mkv) videos on my PC. When the video is playing sometimes it just freezes or plays quickly, but the sound goes on and later the video starts playing properly.
I tried switching to different media players (Movie player, splayer, vlc player) but the same problem occurs.
Also, I reconfigured the graphics card settings but I'm easily able to play HQ games.
Graphics card - ATI Radeon HD3470
PC - Sony VAIO FW
