This is much appreciated.  I have always liked Tivo's 2x and 3x perfectly
smooth fast forward.  (Also, quite nicely, they don't do the reaction-time
compensation at these speeds and only do them at the 20x and 60x speeds)

If you're looking for more to do, I have also always thought it would be
a good idea to enable turning on of closed-captions at 2x speed or 3x
speed, so you can actually watch and follow a show at that speed, since
you can read a lot faster than people can talk.   Possibly even a mode
that shrinks the TV box to create a larger window do do scrolling closed
captions along the side.   I have had DVD players that played sped-up
audio during slow-FF, but this would be even better.
