Buy a player that can do the PAL->NTSC conversion internally. A lot of the "lower" end players can do it, I have an Apex, a Samsung and a Cyberhome player that I have seen do it.
Cyberhome CH-DVD 300 you can get at Walmart or Sams Club for around $40 does the conversion but the aspect ratio gets scewed sometimes. The 400 and 500s are supposed to be better at perserving the aspect ratios. Check out places like
Nerd-out forums and find out which specific players support the conversion..
