Not the answer to your question but something to consider. I was losing video constantly, and after a run would have about 50% of the session spread across 12 separate short clips. Tried changing SD card, no help. Lost video last year of my Mid-Ohio incident so the other guy (whom I think did it on purpose) did not get a 13/13. I'm running a Contour on car power using their adaptor, but with the battery charged, too. Turns out that the vibration in the car was enough to loosen the adaptor in cigarette lighter just enough to stop (and in rare cases corrupt) the video. I ran power wires (fused and on a switch) directly to the adaptor, did a really ghetto connection (between races), and it worked perfectly generating a nice, long 3+ GB file.
Lesson - in a race car, make certain power connections are VERY solid.
