Thanks!
I've just done some test on small files and now I understand how
negative bitrate works. Encoding started, but.. of course I forgot about
audio! Agrr.

Thanks again. I think I cope with this :)

PS. AVI index for 700 MB CD is something about 15 MB, overhead per frame
is 24 (from manual "default: 24 - AVI average overhead").
