humans can cope with with a a few missed frames.  there are many 
factors involved.  if we assume that TV is 26 (iirc) frames/second
there is phosphor persistance on the the screen (let's forget about
LCD's) and (iirc) there's retinal persistance.  so, dropping a
few frames  doesn't really matter.  oh yeah, it's interleaved as
well.

they may not even be watching when the frames are dropped.

if yer talking about military or medical systems they have to
be 'right on time' within certain tolerances.  otherwise yer
F-16 turns into an unflyable mess or your patient dies.

if you wanna build a 'real time' system:

    1. define it
    2. design it
    3. code it
    4. test it till it breaks and should it, goto 1

otherwise, pick up a hammer and go search for some (soft) approximation of a nail's position.

btw: as Seigfried said "WE DON'T DO THAT AT KAOS"
