To answer my own challenge: on *nix MEncoder is also faster on this
file as well. 71.7 versus 57 fps = 25% faster.
Centos 6, Mencoder r35020 with the same Git version of FFmpeg as
on my Windows 7 machine.
ffmpeg version git-2012-07-13-d3abbb1
ffmpeg -i 00005.MTS -vf scale=448:256 -aspect 16:9 -sws_flags bicubic
-vcodec wmv2 -b 336k -r 25 -acodec wmav2 -ab 64k -threads 6
-y 00005ff.wmv
fps= 57
MEncoder SVN-r35020-4.4.6
mencoder -mc 1 -vf scale=448:256,harddup,telecine
-lavdopts fast:threads=6 -of lavf -lavfopts format=asf
-ovc lavc -lavcopts vcodec=wmv2:vbitrate=335
-oac lavc -lavcopts acodec=wmav2:abitrate=64
-o 00005menc.wmv 00005.MTS
143.41fps (50i interlaced frames counting) = 71.7 fps
The really old MEncoder SVN-r31628-4.4.5 is somewhat slower than
the latest FFMpeg: 48fps. But it does not need the extra telecine
filter to produce correct encoded files.

Note: this is a version before the MT merge!
