Ok I uninstalled PTS and trying this new method.
Imagine this scenario:-
I'm watching the news but missed something the guy said. so I rewind 15 seconds, so far so good, I hear what the guy said and now I want to go back to live so I press stop,
this stops the timeshift permanently and no longer records again until changing away from the channel and back again unlike PTS which will carry on recording after pressing stop.
The other way to get back to live is to FF until it catches up.
Both of these seems very clumsy or have I missed something ?
In fact, if you press the stop button alone it deletes the shift.
