I too have the DC100. I just got it a few months ago. So far only two rolls of film threw it, with nothing to show except the same picture of an empty trail. I put the first roll in only to have exytreme wind conditions follow. I don't know if that was the problem. It seemed to work a little by the time stamp, but then it would take a string of pictures of nothing. Next roll I tried to change the direction I had it pointed. Same results. It woud seem to work for a while, then just eat up the balance of the roll. I now have it set in a more poen area, hoping to eliminate any brush movement. I also set it in a more shaded area trying to see if the direct sun is effecting it. I don't know i'm confused!
