My parents gave us their protron portable DVD player - it is old, the battery no longer works, so we have to have it plugged in to watch is. However, the car adapter cord is way too short to reach to the back seat for my daughter to watch it. Where could I get a longer cord? Also, the remote no longer works, but I can't find a battery compartment for it?
