I ran the same command(well, basically) on my system, and it worked just fine 
- but I'm on linux so it might be different on windows(though I don't see why 
it would be). More likely the difference is in the build options.

The blank line in the middle here is where it usually gives some information 
while it is working. I'm not sure why it doesn't output anything, but 
something clearly is wrong. Might be a missing libjpeg as suggested.

If it is available for use, then I believe libjpeg is compiled into mencoder.
If you want to check if it is available, then you can run this command:

mplayer -vc help

and you'll get a (long) list of available codecs. On my system, there are 181 
lines(one codec per line), one of them this one:

ijpg        ijpg      working   Independent JPEG Group's codec  [libjpeg]

which tells me that libjpeg support is compiled in.
If the list gets too long for your screen, you can use this one to get one 
screenful at a time:

mplayer -vc help | more
