wine users - Apr 2009 - IE 6/7 Long Pause Loading YouTube Videos

Hi all,
I'm running Wine 1.1.20 on Ubuntu 9.02 inside Sun's VirtualBox. I used
WineTricks to install IE 6 & Flash 10. Whenever I try to start a YouTube
Video the browser locks up for about 2 minutes, then it plays the video fine.
Once the video's loaded it plays fine. Other flash sites don't have any
issues.

Is this Normal, or maybe a side effect of how I'm running it (Virtual Box)?

Thanks all!
