The ability to scroll back via a TV's to TV programs which have already been shown or even which are already mid way through. Is the program list served up via the antenna, or the connection to the Internet, or maybe a mixture of both?
The problem I am curious about is lots of LG TV owners, including myself, complaining that often the < (back in time) button is absent from the EPG. Is this presented from the antenna, or from an Internet server somewhere?
When missing, sometimes a channel rescan brings it back and its the only way to bring the < symbol back, often turning the set off then on looses the <, though not always, sometimes it proves impossible to get the < for hours and days.
