When watching a video on YouTube it is so slow. When I download the same video locally and watch with the default video player it plays smoothly.
I'm 99% sure that it's video output API related becuase if I set the video player output to X11 it lags exactly like when I watch online with flash player.
I read some docs that stated the flash plugin just can't use XV. Why? Is this still the case? The article is very old and may be things have changed since then.
I tried to play with Enable/Disable hardware acceleration in flash settings - no results.
My video card is not powerful (old hardware).
