Not 800x600.
NTSC only has 486 lines of vertical resolution. VHS chops the vertical
to 240.

So, usual resolution is 768x480 or 640x480 (the former is more
'broadcast').

For interlaced, first the odd scan-lines are displayed, then the even
scan-lines. Thus, if you were going for full 60 fields per second, you'd
need to have them changed over time. So in essence you'd need images at
768x240 at 60 fps.
