No, all NTSC. I started with a capture card and how do DV passthru or hardware MPEG2.

Not myth, spec, research it and be careful of sources whose author(s) get confused by the difference between square and rectangular pixels.
Passthru doesn't give you anything special. NTSC DV does have 4:1:1 colorspace which is horrible for anything with sharp edges so conversion to 4:2:2 with 411Helper for VirtualDub or Reinterpolate411 for AviSynth is wise.
DV camcorders typically will shoot a full 720x480 image. Given an NTSC analog feed, ~704 with 16 letterbox to yield 720.
