...and for "soft-telecine" DVDs, use -ofps 23.976. You can recognize
this by mplayer saying:

demux_mpg: 3:2 TELECINE detected, enabling inverse telecine fx. FPS 
changed to 23.976!

but watch out because some videos switch back and forth. You'll get lots
of duplicate-frame messages if you don't specify the correct output
framerate in mencoder.

For "hard-telecined" content, Rich's detc and ivtc filters can help
immensely. For more information, read the manual and search the mailing-
list archives..
