again?? how many time do I need to tell you that -ofps will convert
the framerate, that defeats the purpose of the telecining process?
If you need to convert the framerate and mencoder skips frames
evidently the source is not encoded at 24000/1001 fps,
and in that case pass the right :tele_src in -mpegopts;
if the source _is_ encoded at 24000/1001 fps and lavc
doesn't accept the framerate due to rounding errors you
must pass -fps, not -ofps
