I tried this on two different film formats, and it did not work without additional options. 1) MPEG-TS 1920x1080: I used these options: mencoder -vf tfields -demuxer lavf -mc 0 -noskip It turned out to be an excelent conversion of *.MTS files to a playable format. 2) For MPEG-PS 720x576: I used these options: mencoder -vf tfields -fps 50 Results are great.
