Was able to do some testing and Video in Motion does work.
Once you have coded Video in Motion on, you have to do a physical button combination to activate it in the HU_MGU.
The combination is to hold the touch knob forward and then hit Media, Home, Media without releasing the touch knob. Video demo here:

I have also added some clarifications to the cheat codes and re-formatted the labels in E-Sys for clarity.
