Try using "-demuxer mov" instead of "-demuxer lavf". demux_mov has
some support for nonzero edit lists.

I tried your sample (but to a file so I could check the sync) and sync
was way off with demux_lavf but ok with demux_mov.

mencoder -demuxer mov desync.mov -ovc raw -oac pcm -o test.avi

You might also try applying On2s patch to demuxer_mov.c. It's supposed
to improve demux_movs edl support -- mov_01_edl_kf_search.diff
