Today I downloaded all of the vids from my K2. That's when I noticed that all of the settings were of the default, and NOT the ones I had set it to. It was now on TS format (instead of mp4), KPH (instead of MPH), and 1 min loop, (instead of 3 min). I had done a search of the forums and saw that a battery inside the DVR could be the culprit. But I've only had the K2 for about 2 months, and the battery should last a lot longer than that unless mine was on a shelf for a long time. How long should the battery in the DVR last? It could have reverted back to default settings after an app update.
