Either in Time Shifting or while Playback of recording, do the following :
Hit Play button. This will bring the time bar on the screen. Now hit volume buttons (left one will rew 20 seconds backwards, right button will few 20 seconds forwards immediately) to achieve the results. Repeated hitting of volumn button will allow quick movement of cursor on the time bar effectively allowing one to move to any point of recording without going through the very slow >> or << buttons !.. Holding the volume button continuously will actually have a very fast cursor movement on time bar.
