Thank you for your post.
I don't know of any iOS screen video activity. However, using my favorite search engine, I did find:
Has anybody found a screen video captture utility for iOS?
A very very late answer, just saw your question today, and it may have been solved and answered somewhere else a long time ago.
We use Reflector to show the iPad on the computer screen, live. And then Snapz Pro for screen recording.
Another great feature with reflector is that it will show an iPad around the screen on the screen. And then you can choose to include this when recording, or you can just take the active screen.
I upgraded to the latest version of Reflector and it has a 'Record' button, so you can record your activity directly from Reflector. This works great!
Afterwards, I use Screenflow to edit the recorded movie (add comments etc.). You could use any movie editor, but Screenflow has some very nice tools especially for this purpose.
