NTSC is only good for 480 visible scanlines.  You can do 640x480 or 720x480
over S-video easily enough, but anything more than that will have to be
downsampled.

As for widescreen, since there's no provision in analog video for signaling
whether something should be displayed standard or widescreen, it's up to the
viewer to set the display appropriately.  If the source video is anamorphic
widescreen and the display can handle widescreen video, the display will
stretch the video out to the correct proportions.  (It's the same thing that
you do when you play a widescreen DVD on a widescreen TV.)
