This what you do. Connect the video wire to a power suppy and install a switch in the power wire. When you put the DVD in and the warning comes up, turn the switch on then off. This will allow you to watch the DVD without the park brake being applied.

Connect the park brake wire to a power supply. Install a switch in the power supply wire you just hooked up. Put DVD in and when warning comes up, turn switch on then off. this will bypass the switch.

Get a relay (4 or 5 pin) from Autozone, O-Reilly, PEP Boys, etc....
Connect wires as follows on relay:
Pin #86 - Amp remote from your radio (blue wire)
Pin #30 and #85 - to a chassis ground (metal dash bracket)
Pin #87 - to Parking brake input wire on your radio (light green)
Pin # 87a - IGNORE. It isn't used in this case.

What this will do is.....
Radio will power on when you turn your key. The amp wire is delayed slightly and will trigger the relay in a second or two. This tricks the radio into thinking your e-brake has been engaged and violla....Mine has worked everyday since I connected it.

ground the wire to a hot (ie power comes to the wire) switch in your dash, like a rear window defroster or seat heater. turn the switch on then off and it will trick the system into thinking you activated the parking brake.
