I have a DCS-2132L B, and I've set the video recording length to 60 seconds. However, the camera refuses to record a single video more than 3-5 seconds. I'm left with a series of fragmented videos that are extremely short. Why is it that this camera will not record any sort of extended length video? Is this a motion sensitivity issue? I've tried playing with the settings, and I can't get the camera to record anything more than 5 seconds, even with constant motion.
