Hi. I recently downloaded BURN for my Mac.  I have a DVD that contains video encoded in PAL and will not play in any of my DVD players here in the States.  I tried to copy the VIDEO_ folder from that PAL DVD to a blank DVD using BURN.  I made sure to go into Preferences and clicked on the Video button and selected NTSC from the drop down.  I then clicked the burn button.  But when the copy was finished the conted was still in PAL format because the new DVD was not playing in any of my DVD players (just on my laptop).  Am I doing something wrong?  Can someone tell me what specific steps need to be taken to conver this PAL video to NTSC using BURN?  Thanks in advance!
