I'm bumping this old thread because I have a similar question and didn't see any other info on this.
I currently have a Philips portable DVD player that I have been using in the car for about 2 years. I'm very happy with it and think the quality is fine for what I paid for it - about $150.
However, we've had some problems using it in the car because it's hard to position so the two second row passengers in my mini van (my 6 and 4 year old kids) sometimes have trouble seeing the screen or we have trouble securing the unit so it does not move when driving.
I would like to have monitors that I can hang from the back of the chairs in front of them. I'm not sure if I can get two external monitors (there is one composite audio/video output mini jack) or if I should get a new unit with two monitors.
I was thinking of getting something like this:
Amazon.com: Philips PET7402/37 7-Inch Dual Screen Portable DVD Player with Car Mount, Black: Electronics
Would I be better off trying to buy external monitors for the unit I have or just buying this one. Suggestions for either one would be appreciated.
