ffmpeg core dumps on FreeBSD 6.2

[Dave]

Hello,
    I've got a cvsupped ports tree and am trying to convert a .avi file to 
.mpg specifically a vcd so i can burn it on to a dvd. I've included the 
command output at the end of this message, both the ffmpeg command and the 
file command showing what freebsd thinks the .avi file is in question. The 
result is the ffmpeg started then core dumped. I've got the .core file if it 
would help, but i'm not a programmer so don't know where to go with this. 
Any assistance is appreciated as i'd really like to get this .avi file 
converted.
Thanks.
Dave.
