The DVD standard is 720x480 (720x576 for PAL). Getting that format unscaled out onto a connected TV is important I guess.
50 or 60 Hz also selects if TV is NTSC or PAL.
Possible, but note that many DVD players on the European market play NTSC DVDs fine and turn them into PAL-60, meaning many TVs available here nowadays also do PAL-60. At least all flat-panel TVs I've seen upto now do.
Yes, they ofcourse also do 50, but PAL-60 is not an unimportant format then. Again, playing NTSC-DVD format video on the connected TV is why you'd like to be able to just do PAL-60 if your TV supports it.
