If you want to convert and burn MTS files to DVD to play well on NTSC DVD player, you just need to use a right software to convert and burn MTS files to NTSC standard video DVD that can be played well on NTSC DVD player, but I don't think there is a good free software can do this well, I tried many free softwares before, but none of them work well, someone don't suppport mts files, someone poor quality, someone even virus, so now I'm using an inexpensive software RZ DVD Creator, it can convert any formats video files to standard video DVD with good quality, and burn to any DVD disc(DVD-R, DVD+R, DVD-RW, DVD+RW, DVD-R DL, DVD+R DL, etc), easy to use, insert a dvd disc into your computer dvd burner drive, run RZ DVD Creator, directly drag and drop your MTS files into the RZ DVD Creator, for some MTS files, you need to enable "Force Source Resize" option in RZ DVD Creator advanced setting dialog to optimize the quality, then select "NTSC-DVD" as target format, and press "START" on, you will get a good NTSC standard video DVD from your MTS files, then you can play the burned standard video DVD well on your NTSC DVD player. You can yahoo or google search RZ DVD Creator and download it, hope it can help you.
