+* Pausing live video
+
+  If you want to pause the live programme you are just watching, simple press
+  "Menu/Yellow" or "Pause" on your remote control. VDR will start an instant
+  recording of the current channel (just as if you had pressed "Menu/Red" or
+  "Record") and immediately begin replaying that recording. Replay will be
+  put into "pause" mode, so you can attend to whatever it was that disturbed
+  your live viewing session. Once you're back, simply press the "Up" or "Play"
+  button and you'll be watching the current channel in time shift mode, right
+  from the point where you left off. The instant recording VDR has started
+  will use the same parameters for priority, lifetime and recording duration
+  as any other instant recording, so by default it will record 3 hours (which
+  should be enough for any normal broadcast).
