Oh I know how that goes. I was at San Diego Comic Con last year and Chris Pine sent a video message and so I have (had) a friend who was a huge fan so I taped some of it for her and I was so nervous I was going to get caught. Then he phoned in so I taped the phone call figuring it would be a minute .. it was like ten. At another panel Jim Parsons was giving acting advice so I taped it, but I was so nervous I forgot that my lens cap was still on so the first 20 seconds are black and you can only hear him talking until I took the cap off. Whoops.
