Their video like laggy laggy like tat hor...
Is my pc problem or wat arh?
I also experienced the same even though I am on fiber optics 200MB broadband and my PC never had any problem watching full HD videos.
Actually not only laggy but the sound of some videos is off sync with the video.
I went around the laggy problem by downloading the video using "download helper" (an addon to my firefox browser) and then, after downloading, play the downloaded video with a video player.
However, on some videos, the sound is off sync by 1 or 2 seconds (faster or slower). So I set the audio time shift to make the sound and video sync together.
In this way, I eliminated the laggy and sound off-sync problems.
