[Solved] Youtube videoes out of sync (audio)

Hey guys.
Some videoes on youtube audio goes out of sync when i skip in the video. Not all.
The audio is “behind” the video.
It is not because the video is ahead, because the video ends exactly where it should.
I tried to disable hardware acceleration, because I think I read somewhere that it might help, anyway it didn’t.
Is it something with my computer or is it the videoes itself?
Answer #1
Install the latest Flash player and install Audio Codecs (K-Lite Codec pack is recommend) and see if it works.
Answer #2
Thanks for input.
Anyway I figured out how to fix this problem.
For some reason the VLC plugin in firefox causes this problem. To avoid this problem simply turn off the plugin.
