I have the above camera and it works fine most of the time. Sometimes after I start to record a video it will stop recording maybe within 10 seconds on its own. Camera stays on. Any ideas? Ok, tried it again this morning. Tried three times and it stopped video again within about 10 seconds. When it stops recording the lcd screen on back says camera busy. When that goes off the screen says low speed card. I have had this card in it since last April and it's worked fine. It's a 16 gb Samsung card. I have no idea what class it is.
