Video clips load slowly

[musique]

Hello,
Hi, if I want to watch a video from say u tube, it moves slowly how can I fix this

first clean everything (use CCleaner)

Then try updating your flash player, or uncheck hardware acceleration by right clicking the video.

It could also be your PC or internet connection, but since I don't know them...
