> Another clew I forgot to post. Opening a Chrome window on the virtual
windows machine kicks the host CPU up to 50% where the XP CPU is showing
only 2%. Opening Firefox or IE uses only 2-5% in the host. Chrome does not
use a standard Window so whatever it uses, is not implemented in VirtualBox
in an efficient way. Probably a similar thing missing that Silverlight
I am basically stuck. Again, I ask is anyone using their Myth box to watch
Netflix with anything short of 100% CPU?
