Running windows 7. No bluetooth app. Checked the SD with the adapter and it's still just 3 videos. I thought I noticed this before but figured I hadn't moved the slider all the way forward so I wasn't recording. Today, I was definitely recording. I don't know if it over wrote them or what but I contacted Contour customer service.
Sounds like somethings wrong there... Have you tried a different memory card? Maybe it just doesn't like the one that's in it.
I haven't lost one video, also leave the beeps enabled so you can be 100% sure when it starts and stops (if you haven't already)
