[MEncoder-users] Videos with fps 1000.000

[totob at libero.it]

I have got a couple of videos whose mplayer -identify says that have a fps of 1000.000 

es: 
1] VIDEO:  [MP43]  320x240  24bpp  1000.000 fps    0.0 kbps ( 0.0 kbyte/s)
2] VIDEO:  [WMV1]  320x240  24bpp  1000.000 fps    0.0 kbps ( 0.0 kbyte/s)

I am encoding to FLV.
The question is: how can i set the encoding final fps in the mencoder option? If i set 1000 the videos encoded are few seconds long. I tried with 15, 29 and 30 but the resulting video is never of the same lenght of the original one.

I am using a command like : 
mencoder -noskip -mc 0 -of lavf -ofps [FPS] -oac mp3lame -srate 44100 -ovc lavc -lavcopts 
vcodec=flv input.avi -o out.flv -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames

Thanks to anyone who can help me!
