That article is pretty much right on the money, but there is even an easier way, given you have the resources...
Shoot on a Canon XL-1 or GL-1 in frame mode, and that creates video that is almost identical to the end product of the processes described above, except better. Why? Because the non-interlaced video is produced in camera with very little resolution loss, as opposed to taking existing video and removing a field.
Using an XL-1, and color correcting in Final Cut, has produced video for me that has fooled many production companies in L.A. here for 16mm. I dare say that it is a poorly kept secret among some DV shooters that the Canon frame mode is the "poor man's 16mm".
