Abysmal change to fast forward function

Fast forward/reverse used to work perfectly, up until a couple weeks ago.  There were 4 or 5 speeds and they were consistent.  It was easy to FF 90 seconds and it would start playing exactly where you hit play.

Now there are 3 speeds, but they start slow and speed up as it moves.  Then when you hit play (to stop FF'ing) it might start playing where you meant, or any time up to 30 seconds before you mean, or sometimes it goes to the end of the buffer like maybe 20 minutes ahead of where you were.

What is up with this?  The old FF worked fine, this new thing is like  regressing to some horrible Tivo system.
