Audio sync problem
I've just viewed the Shackleton video someone posted on R & N and it reminds me of a small problem I have.
Whenever I watch videos such as this and any on YouTube and similar on my main computer, the audio is always out of sync with the visual by about two seconds. I hear the sound first then the matching video comes 2 secs later. Quite annoying when there's a talking head in frame. Videos play/stream perfectly on my two laptops.
Anyone got any ideas as to the cause and what I can do about it?
