I don't know if you intended me to remove the other xvidenc opts... I'm trying 
it without. I assume me_quality=6 was the motion estimation quality? Why would I 
not need that? I guess it uses more CPU time for better ME? I also noticed that 
my GOP was 300 which might explain why seeking was so slow - I'm trying 
max_key_interval=20. I also noticed that whereas previously I had two p-frames 
for each b-frame, and now I have one p-frame for each b-frame - I don't know 
what changed that, or whether it matters.

Anyway, the point is, I still don't see TFF or BFF set. (I don't know if it's a 
property of the container or the datastream, but in either case, gspot doesn't 
report it, so I'm assuming that when I import this stuff into my video studio 
program, I will still need to tell it manually that it's field-B.)

Thanks for your help. Any other ideas?
