In my case it allowed me to select it but on playback it rejected it:

2009-05-02 09:20:01.933 VDP: GetFilteredDeint() : xvmc-blit ->
'fieldorderdoubleprocessdeint'
2009-05-02 09:20:01.934 Failed to approve
'fieldorderdoubleprocessdeint' deinterlacer
2009-05-02 09:20:01.934 Couldn't load deinterlace filter

This is coming from libs/libmythtv/videooutbase.cpp and I'm looking
into it now.  I have a feeling that you're actually falling back to
your secondary deinterlacer or to none at all as was the case for my
profile.  If you add playback to your -v option you can find out.
