FF and RW, Back and Forth Timing

[Fapcha25]

Guys, even if I were an American guy I would not knew how to exactly say this, but let's go: Each DVD or Blu-Ray Player has its own timing, its own fastness and agility to go back and forth, to rewind and fastfoward a disc since you press the RW << or the FF >> button. Take my DVD player, for instance: I barely press the RW or FF button and the disc goes back or forth, the player response is immediate, the rewind or the ff is fast, quick, and is seems to goes frame by frame of the movie, I can watch almost every frame and scene during the rewind for example. I got total control over the RW or FF timing, points and scene, to get to the exactly time I want to, and it's really fast. On the other hand, I got no control, no precision doing that in my Blu-Ray PLayer, a Sony S350. I press the RW button, it seems to take a whole second to just start to go back, the rewind skips lots of frames, I only can see pieces, flashes from the movie, and always stops beyond, further than I wanted to. This must be stupid, meanigless and maybe nonsense for you. However, since I live in Brazil and I use every movie and series to develop and improve my English, I go back and forth several times, watch some scenes over and over again, so, this feature is extremly important to me.
My question: Do you know what is it I talking about? What it takes for a Player to do this, how can I know if it has this feature, before I buy it, and, finally, is there anyway I can update or "fix" my BD PLayer so it can do this? Has this feature an specific name?
