Disable DVD playback lockout while driving?

Has anyone identified the offending wire or another route to disable the lockout feature that keeps you from playing dvds or video material while the vehicle is in motion?

I'm using the Coastal Tech Lockpick on a non-NAV system and using a portable dvd player to test with.

As of right now, the dvd plays just fine while the vehicle is parked but once moving the video display on the MFD shuts down. On most aftermarket units you can simple ground out the "parking brake" wire to bypass this safety feature.

I'm well aware of the dangers of watching dvd while I am driving. I've had video systems in my cars since 1994 and know better than to watch them myself.
