DVR enables you to record live TV on a USB storage device while viewing a
digital broadcast. You can watch segments of the programme you missed later
and resume viewing from where you left off, even if you have been away from
TV for a while.
✎ The Timeshift mode can be set up to 90 minutes. (For Italy, it can be set for
up to 60 minutes.)
✎ If there is problem with a data sector on the USB storage device, it may not
work properly.
