60Hz would be enough for NTSC playback without time-stretch, but
it needs to be >= twice the framerate. Sometimes its just a few
milliseconds under that and fiddling with the modelines can make
it work (there is lots of info on this in the mythtv users mailing
list archive).

Linear blend and kernel deinterlacing should work for any of the
software decoders, while XvMC only accepts bob and one-field
deinterlacing. The video profiles editor should only allow you to
select deinterlacers which at least can be valid when the moons
are aligned. If it is allowing you to configure kernel deint for
XvMC that is a bug.
