OK, the above is the tail end of the output on the *working* machine 
when it encodes the video.

Using the -v flag on the *non-working* version of mencoder, this is the 
last thing that appears on screen ..

The full command line:

mencoder -v new_montage.MPG -o ~/new_montage.flv -of lavf -lavfopts 
i_certify_that_my_video_stream_does_not_use_b_frames -oac mp3lame 
-lameopts abr:br=56 -ovc lavc -lavcopts 
vcodec=flv:vbitrate=250:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050

Looking at the two configure.logs (not that I really know what I'm 
looking for) I can see that the working version is using libmp3lame 
3.93, and the non-working version is using 3.9.7. Don't know if that's 
significant.

Other differences include cc 3.3 on the working version, cc 4.1.2 on the 
non-working version .. although I assumed that the "Don't use new gcc 
versions" warning was no longer in effect.

Anyhow, I've attached both logs to this message (assuming it won't cause 
it to be rejected) in case somebody can take a look and spot something 
obviously wrong.

Cheers,
