(I own the box)

This will actually resample it to 23.976 fps and rescale it. This would 
be the bare minimum (leaving the x264opts intact):

"C:\Downloads\MPlayer-athlon-xp-svn-32492-mt\MPlayer-athlon-xp-svn-32492-mt\mencoder.exe" 
"E:\a.M2TS" -o "E:\Enc_Out\a.avi" -ovc x264 -x264encopts

-oac copy -mc 0 -fps 60000/1001

You can also use my little frontend YAMF which has a profile for that box.

I have converted dozens of movies this way. I had to tinker for a while 
to get it to work.

I strongly suggest the first downsample option.
