+# Timeshift works the following way:
+# demux0 demux1 "TimeshiftActions" "TimeshiftActivateActions" "SeekActions"
+# - normal playback TUNER unused PLAY enable disable disable
+# - user presses "yellow" button. TUNER record PAUSE enable disable enable
+# - user presess pause again FILE record PLAY enable disable enable
+# - user fast forwards FILE record FF enable disable enable
+# - end of timeshift buffer reached TUNER record PLAY enable enable disable
+# - user backwards FILE record BACK # !! enable disable enable
+#
+
+# in other words:
+# - when a service is playing, pressing the "timeshiftStart" button ("yellow") enables recording ("enables timeshift"),
+# freezes the picture (to indicate timeshift), sets timeshiftMode ("activates timeshift")
+# now, the service becomes seekable, so "SeekActions" are enabled, "TimeshiftEnableActions" are disabled.
+# - the user can now PVR around
+# - if it hits the end, the service goes into live mode ("deactivates timeshift", it's of course still "enabled")
+# the service looses it's "seekable" state. It can still be paused, but just to activate timeshift right
+# after!
+# the seek actions will be disabled, but the timeshiftActivateActions will be enabled
+# - if the user rewinds, or press pause, timeshift will be activated again
+
+# note that a timeshift can be enabled ("recording") and
+# activated (currently time-shifting).
