Why do you use -mc 0? You do realize this completely disables
mencoder's A/V sync algo? And in case you play with the frame rate (as
you do) it will only make things worse!

and why do you want to create a true 24 fps film file?

Still, if you want 24fps file, use -vf
filmdint=fast=0/io=25:24/dint_thres=256 -ofps 24

Also, your file will be broken since you haven't disabled b-frames in
your x264 line (which are on by default) and you're using the lavf
muxer to output which is broken with b-frames + mencoder
