If region coding wasn't confusing enough - many countries have a different video standard (the way the actual video signal gets to your TV). The two main power frequencies widely used arround the World, 50Hz and 60Hz divide the World's TV systems into two distinct systems: the 25 frames per second system (50Hz) and the 30 frames per second system (60Hz). PAL will NOT play in an NTSC VCR / DVD player (and vice versa) without a video signal converter or internal converting hardware inside the VCR / DVD player (not a common feature on consumer players). We carry multi-standard DVD players and VCRs for rent that convert all of the different signals digitally. There is no difference in quality from the orginal video signal during these conversions.

Computer DVD drives are PAL/NTSC-indifferent, i.e., a computer DVD drive can play both PAL and NTSC DVDs.
