Screen Recording

This is probably a blatantly obvious one but it's making my head hurt.

On Snow Lion when I used to do screen recording/web casts I could use the zoom with scroll wheel/mouse and it would be recoreded in the video. Example in my video here: http://www.youtube.com/watch?v=VTgXIWQlMMo

No when I do screen recording in LION it totally ignores the zoom.... Anyone know how to enable it so the zooming is recorded please?

Thanks 🙂
