[MPlayer-users] splitting avi output

[vin.gui]

I want to make a avi file that would fit on 2 cds.
I successfully encoded a dvd into a 1400MB avi file,
then I used avisplit to split it, but the audio is way out
of sync. I read somewhere that constant bitrate mp3 was required
but this is what I used.
At transcode-users mailing list, they say that
avisplit cannot split anything that is not produced by transcode...

Is there a way to make mencoder split the avi file ?
Or can anybody indicate me an alternate solution (under linux)?
(under windows, virtualdub works fine).

Many thanks

Vincent.
