This is probably my 4th or 5th NT50B that I've had trouble with. It won't take videos or pics and when watching the IR array with my cell phone camera all the emitters will light for a split second and then one second later only the bottom half of the emitters will flash for a split second. It will take a pic with the shot button but that's the only way. I've tried two different SD cards with no difference. I was thinking these had a default option on the remote but guess I'm thinking about my SG560. Anybody else had this problem? BTW I had the video set for 30 seconds and the photo burst for 9.
Here's a video I recorded with my cell phone.
