Use one of the following:

mencoder -ofps 23.976 -vf softpulldown,detc=dr=1 ...
mencoder -ofps 23.976 -vf softpulldown,ivtc=1 ...
mencoder -vf pullup ...

Note that the (very new) pullup filter is NOT complete yet, and will
not behave right with -ofps 23.976. It might even crash. :) Also, the
algorithms that decide how to put clean frames together are not yet
complete, so it's bound to mess up a bit at scene changes... But one
very nice thing is: it's capable of handling mixed hard-telecine,
soft-telecine, and 30fps content in the same stream! Pullup will work
much better in G2 (once G2 has an encoder) with variable-fps output
formats instead of avi. So, if you'd like to experiment with pullup
and report your results, that would be cool....but for reliable
ripping, one of the other options is better for the time being.
