      With is not used at all... Flash doesn't support it (yet).

      I know very well how he did it and I will implement it some day, but
      this works only for Flash 9. Flash 9 install base is currently around
      15%-25% and those people with Flash 9 also have QT or something else!
      Mine works with Flash 8 and this is a much larger audience. If you
      look close to the other player than you see that he simple blurs the
      image while spinning... I can do this too if you like... than you also
      don't see waves because you can't see edges ;)))

      But as you mention there are to many variables like wavyness,
      interpolation method etc. You can not get exactly the same results
      from each player so 25 fps for Flash are void for you because waves
      are a don't go, others don't care that much. All players have their
      pros and cons. There is not one "perfect player". This could only be a
      guideline. If you look at something like
      than Flash is a good alternative to other technologies and I hope I
      can squeeze out as much as possible. The next version will hopefully
      be at least 10% faster due to some further optimizations.
