Well if I use 1.0pre7 with the same command line (adding -vf harddup and 
keyint=25 as suggested) I get:

$ ~/downloads/mplayer/MPlayer-1.0pre7/mencoder -vf harddup -noskip -of
mpeg -mpegopts format=mpeg1 -ovc lavc -lavcopts 
vcodec=mpeg1video:keyint=25 -o PC290052.mpg PC290052.MOV

   <snip>

[mpeg1video @ 0x8602a38]MPEG1/2 doesnt support 15/1 fps
Could not open codec.
FATAL: Cannot initialize video driver.
 
Exiting...

So I do not know if anyone noticed whether the MOV file was 15fps or not.

If I set -ofps 24000/1001 I get a mpeg1 video that works!!!!! No Error SCRs.

However, it runs 18 seconds instead of 28 seconds for the MOV. Sounds 
like I am stuck? Or is there a way to duplicate each frame and run at 
30000/1001?
