It seems to work quite nicely:
mencoder BMS.S01E02.ts -msglevel all=0:statusline=5 -demuxer lavf -aid 1
-vc ffh264 -fps 60000/1001 -ofps 24000/1001 -of avi -oac copy -ovc x264
-x264encopts

I didn't need to run the original AVC stream through ffmpeg or use -mc 0
or -noskip. No more duplicate frames or interlacing and it's the
original 24000/1001fps it should be. Maybe I'm just so used to working
with pro wrestling which requires an insane number of bits, especially
at 1920x1080, but  5387kbps (the average bitrate I got for episode 1)
seems low to me. In any case, I can't notice any artifacting that wasn't
present in the original and it looks pretty good for HDTV.
