correct.

i don't think xine-ui uses it, unless it is fallback mechanism to old
xine-lib versions.

no, XINE_PARAM_VO_DEINTERLACE is deprecated for the frontend. it does
not load tvtime and may only enable the old method implemented in our
XV driver. the reason it still exist is to allow enabling hardware
deinterlacer support (as provided by some vo driver).

for example, if you decode mpeg streams with hardware acceleration
(xvmc, xxmc) xine won't be able to process frames' contents. the only
way to deinterlace is to ask xvmc/xxmc driver to do it. in other
words: load tvtime and set method to "vo_driver". this will set
XINE_PARAM_VO_DEINTERLACE internally.
