OK, so I try mplex and get "ERROR: [mplex] MUX STATUS: Frame data 
under-runs detected!"

I know this is not a mplex lsit, but I am usinf mencoder to get the m1v 
file.

Here is what I tried:

mencoder mf://*.jpg -mf type=jpeg:fps=24 -vf harddup -ofps 24000/1001 
-of rawvideo -mpegopts format=mpeg1 -ovc lavc -lavcopts 
vcodec=mpeg1video:keyint=25 -o test.m1v

<no ERROR: SCR: 's !!!>
