i had 2 dvd players (cheap ones, so dont listen to the reviews by some planks who say dont buy cheap)and this system was easy to set up and had it working in minutes. here is the kicker, i replaced my dvd players with dvd recorders and now cannot get this interactv system to work on either, i phoned the helpline number and they told me that this is a common problem. so if you have a relatively new dvd player be prepared to return this item as mattel is not offering any new codes, so if the ones in the book and the manual code input doesnt work for you, you knackered.there is nothing i like more than throwing my hard earned money away to multi million pound companies, thanks for creating a toy that clearly doesnt work on all platforms.the moral is, this worked well on all my cheap and nasty dvd players, not on my good expensive ones.
