Thanks, Carl. I'm going to respond first to the most global 
architectural issue (as I'm able to recognize issues and discriminate 
between them).

If ffmpeg doesn't know about fields, how can it decode interlaced content?

- Mark.

PS: I'm retired, but in a prior life I actually designed some video 
hardware, NTSC (Atari research) & satellite gear (FPGA chips for HDTV 
distribution), but the problem I have is interpreting what appears to me 
to be inconsistent or ad hoc terminology in ff-docs. I'm attempting to 
develop a video recognizer useful for preselecting HandBrake presets. So 
far I've been wildly successful, but I have a few loose ends. I will 
follow this message with specific questions regarding the details you 
addressed, okay? - Thanks again.
