After reading your reply I started to think that might have been my case as well, but after setting the time and swapping out a couple of batteries I shot a football game today I went home and started capturing it to see if it was going to mark each scene. Turns out it was because of the date, each scene was marked and spliced. But I never turned off the date it has always been on so may be my internal battery is getting low and I need to plug it in and charge it for 24 hours. It really sucks having to splice a wedding from start to finish, that makes the project a whole lot harder to get finish in timely manner. Is there a warning in the cameras that gives an indication if its getting low? If not this would be a helpful tool to have in the camera. I love my Sony PD150 and my PD170, and Vgeas pro 8 is awsome.
