If your input isn't exactly the right framerate when encoding to mpeg1/2, mencoder will exit with that error you are reporting.  No idea why "expand" would change the frame-rate, though...  

This is with mplayer version MPlayer dev-CVS-050308-12:39-3.3.5 (Updated 
and compiled today to see if it fixes anything)

I did as you suggested. In fact I stript the command down to:
mencoder -vf scale=0:0:0:0:0:0:pal -ovc lavc -oac copy -o 1.avi 
some_avifile.avi (vith ore without -ofps 25 did'ent matter)
And I still get the error, I tryed with various differnt avi/mpeg files.

I also found out it's not limited to mencoder. The same happens with 
mplayer. mplayer -vf scale=0:0:0:0:0:0:pal some_avifile.avi

I have also mplayer version 1.0pre6-3.3.4 installed. And with that 
version the 2 abow commands work.

I'll start reading the bugreport howto. In case it still sounds like a bug!

> "buffer underflow" is just a minor warning, and nothing to be concerned about.
