[MPlayer-users] Size of avi index

[Jeroen]

Hello,

I have the following question:

I understand that the index of a avi file is located at the end of the file, 
but how large is it?

The reason I ask is the following:

I'm trying to make a 704 mb movie, into a 700 mb movie, to make it fit on a 
cdrom without overburning. I used the split program for that, like this: 
split -b 700m movie.avi. The result is a 700mb-movie.avi. So far so good.

After that it needs a new index, so I do:

mencoder -idx 700mb-movie.avi ovc copy -oac copy -o movie-fixed.avi.

You don't believe it, but the movie-fixed.avi is again 704 mb :-(.

How come?
