TyTN video camera bug when no review period?

I took my kids to an amusement park with only my TyTN for pictures, and set the camera settings to have no review period so I could take pictures one right after the other.

But when I did that, video clips simply disappeared.

I then set it back to 3 second review, and it worked fine.

The problem seems to only be for videos, not still pictures. The clips might still exist, but they're not in the My Videos folder. I noticed that the picture numbers were incremented as if the missing clips did exist.

Has anyone had this problem on the TyTN or similar device?
