I did the following, and I can't record a Youtube video

1. I started Replay AV 8
2. I clicked "Open Recording Wizard".
3. I clicked "Record something right now".
4. I clicked "Capture a Video clip or Audio archive from the internet".
5. I clicked "Clear List" button.
6. I clicked the "Done" button.
7. I went to Youtube, loaded the video, and started it playing.
8. I repeated steps 2 to 4, and the Youtube video is NOT showing in the list.

I tried this in Firefox 3 and IE 7. Neither are working. What gives?
