[MEncoder-users] Xvid bff/tff field order issue

I posted a patch that inserts tff flag into xvid. I posted even a patch
showing tff/bff flag while playing videos. The crew was not interested
in fixing this entry. Generally they don't care about interlacing videos.
Although I was not satisfied with ignoring my work, I finally decided to
switch to non-interlaced archives. They convinced me to do so and now I
have better quality movies than before. Still I have my mplayer
corrected to be able to encode tff xvid.
Now I noticed gmane search engine doesn't work well and even it ignores
my posts. This problem is reported in another mail.
You can see my 4 posts regarding xvid interlacing on archive of Sep 2010.

> I am confused.
> Could somebody please do me the favor to check out these 10 sec. video clips ?
> And let me know whether they play fine on your interlaced TV?
> H_.mpg (7.14MB) is the original tff PAL input file. It plays fine on my computer as well as on my TV.
> H_fd0.avi (2.99MB) is bff encoded with mencoder -ovc xvid -xvidencopts profile=asp5:.... without -vf phase=t
> H_new.avi (2.99MB) is tff encoded with the patched mencoder.
> Both AVIs play fine on my progressive display but jumpy on my analog TV.
> You can get the same files also from here:
> I would very much appreciate any hints, ideas, advice...
