        Not sure if this will make it to comp.sys.amiga.tech, but here
      goes anyway...:^).   (My last two postings bounced!)

        Anyway, I just wanted to point out a peice of flawed reasoning I had
      seen.

        Someone had concluded that in order to remove "jitter" (as currently
      being discussed elsewhere in this thread) from 120hz double buffered
      flicker fixing it would be necessary to interpolate intermediate
      fields using specialized hardware.  Note however, that since the frame
      rate is so high, the "jitter" will be imperceptable and at any given
      time two full fields will appear to be displayed at once with no
      flicker.  Even though the images will in fact be moving in a stuttering
      manner to the viewer it will appear as smooth motion.

        The point is that simply double buffering the RGB out should do the
      trick.  Seems to me that if it were done properly it would be an 
      independant product, working on any system which can provide RGB
      (digital) output.


                                                    Thanks,


                                                                Wade.
