[MPlayer-users] Cutting up .AVI's

Hi,

I have a file.avi sized 1481478144 bytes. Codec: DX50 (DivX 5)
It's run-length is 5165.1 seconds, according to mplayer.

If I do:
$ mencoder -ovc copy -oac copy -endpos 2583 -o part1.avi file.avi
and then
$ mencoder -ovc copy -oac copy -ss 2582 -o part2.avi file.avi

I get two parts, one sized ~600MB the other ~800MB. I suppose this
happens because of some kind of VBR-Video-Codec? 

So I tried this:
$ mencoder -ovc copy -oac copy -endpos 706mb -o part1.avi file.avi
and then
$ mencoder -ovc copy -oac copy -ss 706mb -o part2.avi file.avi

And I get two parts, one sized 708MB, the other (!!) 1.3GIG!

Why does this happen? What am I doing wrong? How am I supposed to cut
such a large AVI file into two parts? (w/o using VisualDub in Windows)

Regards,
Sander.
