I installed a dashcam last weekend. Worked great. A couple of days ago went to pull some footage and realized that after 4 days or so all the movie files are not playable. So I stuck a different SD card in it, after less than a day went through all the movies, all played but one. WTF? What use is a dashcam if it's not reliable? Is anyone else experiencing this issue? I'm on firmware 2.004 (July 1). Just wanted to check with more people if there is a simple solution before sending it back.
