The video standard for the US is NTSC. To play a disc in the European video standard of PAL you either need a DVD player that will convert it or a television that can accept it. In addition you have an additional problem with the regional coding. The US is region 1 and the players can handle region 0 and region 1 discs. To play a disc that is region 2 you need a region free player.
Here are some threads that might help you out. One on European discs and there is some talk in this thread on VHS vs. DVD that might help you.
