Why does youtube lose the buffered part of a video when i try to rewind or fast forward?

[JustinX]

Sounds like this might be related to DASH (Dynamic Adaptive Streaming over HTTP). You can disable DASH playback with a browser extension like YouTube Center.

I was having the same problem with Firefox when playing YouTube videos but now it is already SOLVED.
The solution is very simple. Using your Firefox browser you just have to visit YouTube link http/www.youtube.com/html5 and click
on "Request The HTML5 Player" button.
