A field can be dropped by simply ignoring a repeat flag.

[Aa][Ab][Bc][Cd]...

Drop a field:

[Aa][Bb][Cc]...

Fields remain in the proper places.

If there are no repeats then frames can be dropped.

The beauty of jackei's algorithm is that it brilliantly manages the complexity and thereby forces film rate output, regardless of the actual repeat flags present. The way I figured it out was to compare the input fields to the table created in mpeg2source(). As I mentioned earlier, the magic is in the table.
