Sorry, can't watch the videos at work, but I was just curious about a couple of things - first, do you have a picture of the driver/power section? And second, does the TVS diode temp behavior change in anyway with the scope disconnected? If it's unchanged, that would at least eliminate the scope as a source of problems. Maybe you've already done that...

Also, I suspect the spiking may get worse with higher bus voltage - was there a difference between 12v and 24v?
