mozno postaci do lavcopts pridat option autoaspect. Mimochocom v
dokumentacii je informacia o tom, ze zatialco hlavicka MPG suboru obsahuje
polozu pre aspect, AVI ju neobsahuje. mencoder vie sice narvat aspect do
mpeg4 streamu, to vsak vie zobrazit len malo playerov (mplayer ano).

Ja by som volil codec mpeg4 a vypustil "-vf scale". Takze by som pouzil
parametre povodneho postera, akurat pridal autoaspect a mozno zmenil mbd na
2.
