But to my understanding, "-ovc copy" does what it is supposed to do --- it copies the data into the avi container. It does not modify it, so I guess the -idx and -forceidx options are ignored. Furthermore, if you wish to crop the black bands above and below a movie, you ussualy can use "-vf crop=720:480:18:10" (or similar), but in the case of copying that is also ignored. A possible workaround is to make a copy as you did, and then afterwards reencode the file using "-ovc lavc" (and suitable options) into DivX4. The -idx option will work with reencoding, and you will be able to seek through the resulting file, as usual. I do this on a daily basis. But simple copying just copies the data, no modification possible (afaik). And yes, you *are* able to seek when playing the original media, but I assume that is because the seeking method is different than the one in the avi file (no index needed etc...). Maybe the more appropriate place to ask is some mplayer e-mail list. :-) HTH, :-) Marko Marko Vojinovic Institute of Physics University of Belgrade ====================== e-mail: vmarko@xxxxxxxxxxxx
