Sorry - took a road trip to Malaysia for a few days.

Try the attached (against svn). This should give you a new CPU based
'Interlaced (2x)' deinterlacer option. Not tested extensively, and
still needs some refinement, but appears to be working as expected.

Re-reading the above, it has also occurred to me that you won't be
able to use XvMC with this as you can't filter an XvMC/partially
decoded frame. But see what results you get and get back to me.
