Maybe it's staring at me in the face, but i don't see it?
In the Info Inspector > Settings View:
Set Settings View from the dropdown at the bottom of the pane:
You can add Deinterlace to the other views by selecting Edit Metadata View from that same dropdown.
Regretablly this does nothing at all as far as I can see. You can only switch off interlacing for a project, not a clip by clip basis as far as I can find.
The only thing that seems to change is the frame rate and file designation to 1080p.
