I have an HD video files (1920x1080 H.264 DUAL AUDIO FLAC)
file type: MKV
file size: 1.25 GB
file length: 24 minutes

the problem is the video output is not synchronized with audio output,
something slow too much sometime it gets too fast

I tried running it on Windows Media Player , Media Player Classic , and a few other players,
but the result is the same

Additional Info: for device information I'm on LG S510 labtop

The main problem is the graphic processing capability of your computer.

Try upgrading your graphics card, or try playing that video on an 1GB Nvidia.
