To expand on this slightly, it is possible to recover a perfect 1080p24 
signal from a telecine 1080i film broadcast (ignoring bad edits and 
other encoding issues). Thus you can get a full progressive 1920x1080 
24fps out of a telecine 1080i broadcast, which is clearly superior to 
the 1280x720 24fps you would ideally get from 720p (assuming of course 
that the encoding bitrate is high enough to support the increased 
resolution, which is not at all a given.) Unfortunately as I understand 
it mythtv's inverse telecine capabilities are currently pretty limited, 
but regardless of any player issues 1080i gives a much higher resolution 
for telecine film (e.g. movies) content.
