What camera did you use?
Canon PowerShot D10 Water Proof to 33 ft - http://www.amazon.com/dp/B001SER460/?tag=reefs04-20
I did take the camera to twice its maximum depth of 20 meters (63ft) and the mic broke as a result rendering no audio for subsequent recording. That was reckless on my part. However it still took photos and record videos fine.
