For LIVE TV pause, you need to plug in a USB flash drive 16GB or larger. Then it will pause and play up to 90 minutes of live TV on just the channel it's on when you pause it. If you change the channel it resets to zero. If you turn off the TV it resets to zero when you turn it back on. No changing channels, no on and off. It will rewind or pause live TV on the channel you are watching.
