3-4. Trick Mode Operation
If you are watching a service while it is being recorded, or change to a
service which is already being recorded, you can perform the same
trick-mode operations as for time-shifting and file playback (see “Movie
Playback” section in Chapter 6). This applies even if the time-shift
function has been disabled in the Setup menu (see “Time-shifting”
section in Chapter 9).
