  32. Hmmm, I was thinking that it seemed like they were speeding up the feed
  33. slightly.  I was watching the diving and swimming competitions and noticed
  34. what seemed like fast forward shots.  Is it possible they are doing a 10%
  35. speedup or so to also reduce broadcast time?  This would either save them
  36. bandwidth or allow them to make more 'complete' coverage.
