I build my own. I can send you a link using yousendit.com. You should set
up your computer so that you can do it yourself. It is very tiresome, but
you only have to do it once.

Be careful what you ask for .... Unfortunately, most of mencoder's output means
nothing to me.
Maybe someone else will see the problem.

You don't need to upload the whole file. You can use dd (a version for 
Windows is at
http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd-old.htm 
- look near the end of the page)

dd bs=1024 count=5120 if=infile.mov of=outfile.mov

will give you  5120 blocks (where block size = 1024 bytes) = 5 MB.

Just send enough so that the problem can be reproduced. I have given as much
help as I can though. Maybe my test was too short.

Also, there is a mencoder user's list. You might get more help if you
post there.
