Do you see a visual difference between the two encodings? If not then the result 
is ok. I assume that mencoder with 2 pass encoding is far more efficient than 
mpeg2enc. But I don't really know what happens with mpeg2enc when you change 
the quantizer. You should get more similar results in size if you use the
default quantizer (8).
