Mine runs in slow motion. The audio is fine but the video is not.
No vids are really out of sync.

Besides upgrading flash if you already havn't, all I can say is that at times youtube is very wonky.
try watching the videos in firefox or chrome and see if you get the same issues.
Those two vids ran fine for me. As I and other have said, however, sometimes youtube is very buggy at times. It doesn't have much to do with your computer's specs or internet connection, but more to do with youtube's servers. I can personally attest to vids running slow (from a streaming standpoint) or audio going out of sync at times.
Interesting contrast in those two vids you got there.
