При просмотре файла hex-вьером можно найти несколько заголовков avi (заголовок
riff один, естественно).

Hет, конечно. Первые несколько мегабайт.
Только первую секцию, ту, которую получается взять по
mencoder -oac copy -ovc copy

mplayer -nosound -v 111.avi у меня дома под виндами (понадобилось собрать, когда
vdub не смог открыть файл в 2.8Г):

Вырезал из вывода повторяющиеся строки (оригинальный файл занимал 144к, так что
я сомневаюсь, что это пройдет по фидо).
VM> Альтернативные аудио-потоки в avi бывают, а видео- что-то не встречал.
VM> Только в mpg и asf.
Это не альтернативные потоки, это похоже на cat 1.avi 2.avi 3.avi >video.avi
VM> Если ты смотрел файл внутри, как там расположены эти куски и индекс?
Куски расположены последовательно. А как посмотреть индекс - не знаю.
Good luck.
