# 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
