Yea, I have it too. The authorname doesn’t show up on the author pages either.
I can confirm. When clicking the update button, the new data entered into the headspace fields isn’t saved.
In order for it to work on the Edit Post panel, I need to first empty the fields, and retype the data. Then, the Update button has an effect on saving that data.
Also, flash-video-resizer.php should have “Do not resize video of this article.” in line 81.
