It looks like you and the folks chiming in have done some pretty good troubleshooting.
I really doubt that Clive would have implemented the 5V regulator resistor hack (step 42 in the PinWiki). Clive is a solid tech from what I hear.
Have you repinned the female connector at J101 and J129?

I wouldn't be too concerned about 5.1 or 5.2. No big deal.
The power level is dipping when the reset occurs.
Without the mods, power might be just enough. With the mods, more power is pulled, and "just enough" is no longer enough.
If you look through the back of those connectors, and the are bronze colored, they need to be replaced.

Well...before doing that, I'd replace the 5V filter cap.
Since you've inspected the connectors, that's about all that is left.
Clive probably tested that cap with an ESR meter and it tested good. Still, that would be my next step. They aren't easy to get out...you may pull the through holes.
If you want to send it to me, I can take care of it, and test the board in my AFM.

Quoted from Skins:Additionally, I threw in a a kahr 5v daughter board (not for this video) and all resetting went away even with both ung boards in place.
This is the smoking gun.
The Kahr board uses the 12V power circuit to create 5VDC. It's an alternate path to create 5VDC. That means that the regular path on your driver board can't handle the load on the 5V circuit.

Quoted from Skins:So when you say "regular path" that its on the driver board itself?
Yes, via the 5V regulator on the board. It's an LM317 IIRC.
