Along with never getting the sound to work, another problem was that most of what I recorded would mysteriously disappear. I think it was cutting off the ends of all the videos I tried to make. So after recording a minute or two answer what resulted was 15 seconds of soundless video. So that's what they'll see. I guess they will never know who my favorite physicist is. Were your problems with it anything like what I described?
If you're concerned, it might still be worth it to contact them about it? I really don't know.
