Igen-igen divx avi, csak osszefuztem avimerge-el ket kisebb (ugyancsak 
divx) avit (remelem ez nem ront a helyzeten, marmint, hogy avimerge-t 
hasznaltam).

Elnezest, maris irom (nagyon hosszu):

sh$  mencoder -v \
      -ovc lavc \
      -lavcopts vcodec=mpeg2video:vbitrate=988:vhq \
      -ofps 25 -vf scale=480:192,expand=480:576:0:192:0 \
      -sws 9 -oac pcm "film__.avi" -of mpeg -o "film__.mpg"

Es ettol nekem felnem kell, vagy ez csak olyan artatlan kis uzenet, 
amivel nem is igazan kene torodnom. Esetleg emiatt lehet, hogy csuszik a 
hang?

Igen, Dénes mester scriptjet neztem, aztan abban is pcm volt, gondoltam 
nem arthat, regen copy volt helyette. De most jut csak eszembe, az jo 
otlet egyaltalan, hogy az avinak a hangjat dumpolon, es azt konvertalom 
at mp2-be (majd multiplexelem az m2v-vel), ahelyett, hogy a -oac pcm -el 
nyert - hatalmas - hangfajlt tomoritenem be mp2-ben? Emiatt mar csuszhat 
a hang igaz? Szal jobb lenne ha a pcm-es hangot konvertalnam nem?

Ertelek. Nagyon halas vagyok es koszonom a gyors valaszt, rogton 
kiprobalom, hogy -aoc pcm helyett mp3lame -t irok.
