Mencoder with same quality output

I like mencoder for converting video files because it shows me how much time is remaining to the end of the conversion (in opposite to ffmpeg). mencoder file.wmv -ofps 23.976 -ovc lavc -oac copy -o file.avi The problem is that the resulting file is not the same quality as the input file. With ffmpeg there is sameq option. Is there similar option for mencoder to achieve the same quality? Is this only my feeling or is mencoder faster than ffmpeg when I will achieve the same quality? thank you
