Hi Parish,
The problem is that you are returned to the live broadcast at the scheduled end of the program regardless of whether you've caught up.
For example, you're watching a program from 8.30 to 9.00.
You pause at 8.45 and continue watching 5 minutes later.
Your playback should continue for 15 minutes ending at 9.05. However, at 9.00 the box will switch back to live broadcast and you miss the last 5 minutes of the program.
So technically, pressing pause does work but its totally useless in operation.
Do you not have this issue?
