DVD Bypass for front Screen

Has anyone figured out how to bypass the DVD video block to the front television screen? Please advise...

I'm asuming that you have an aftermarket headunit. If so all you need to do is locate the wire that is suppose to be hooked up to the parking brake and connect it to a constant ground source. Your dvd's will noe play at any time you want. I hope that was a help to you. I'm new on this forum so any feedback is cool.

I think he's referring to the new RR Sports with DVD-Video, that you can only watch when the car is NOT IN MOTION.
This is a factory dvd player.

Is there a way to bypass it while driving?
