405 to 625 conversion

[ppppenguin]

It's an annoyance that while a monitor doesn't need to know anything of the odd/even field sequence a standards converter does. At least I think it does. In my case I wonder if I could change it from a framestore to a fieldstore. Not sure how the output side would know which field is which, for sync insertion. In Frank's case with only line stores, the output field is, by definition, the same as the input. Perhaps something is possible? I think not.
