Another tip I had today was to record in MP2 format and not MP4 format. If the DVR recorder is cut short by a power failure (battery goes flat or spikes) the file isn't corrupted in MP2 but it is in MP4. I have had too much experience of this so far so will be trying that out with my new multi camera DVR recorder which should arrive tomorrow. It had better work, I have had two fab races which would have been action action all the way but the files corrupted due to power interruptions.
