Also, since Attack of the Clones was a movie to start with, maybe it was 
broadcast as 720p24 instead of 720p60.  (Movies are filmed at 24fps, so 
broadcasting at higher refresh rates wouldn't add anything--it's only 
done with NTSC since NTSC only allows one format.).  If so it seems 
sensible that 720p24 would take about half the bandwidth of 720p60...
