My only issue is when one player is playing the game DVD it wont let you view a movie on the other screen from the other DVD player. (The game like boots into the dvd player memory) Other than that if you take the DVD out You can play a DVD in one player and watch it on both. Each player will transmit the sound wirelessley to your car stereo. If you do it with both players at the same time it will play distortion noise, so only use one player to FMTX. The kids are really happy with these so it was definitely a good buy for the price!
