I've been having intermittent issues with file corruption - they will not open at all. About 90% of the files are having this problem. I've read other posts regarding this - and as a result - checked all the cables. I had the BMW Motorrad dealer initially install the power, and all power connections still look super-solid. The DVR powers up 100% of the time, as well as both cams. I'm basically dead in the water here and could use some good advice on how to proceed. Thank you.
