I cannot successfully add Google Video to my blog…

Hello,
I am having problems with the WYSIWYG editor that comes with WordPress version 2.x. I cannot add code such as that from video.google.com. If I insert it into the {html} popup screen and publish the post, there is just a big, blank space.

An example of this can be found on my blog — https://www.machet.com.au/blog/?cat=4 The last two posts were inserted using WordPress version 1.5.x, and the most recent comes from WordPress 2.x.

Is anyone else having problems like these? How can I go around this without removing WordPress 2.x’s awesome editor?

Thanks!
