Just taken delivery of a new 4K UHD box with the Big Sport package, but the rewind live tv function does not work. I have tried rebooting via Settings and by using the box top buttons but to no avail.
If it helps, when watching Freeview channels, pressing the rewind button results in a small box at the bottom left of the screen which flashes "x2, x6, x12, x30, >play", in sequence. The screen rewinds briefly, then plays the brief sequence over again, for as long as the rewind button is pressed.
When watching the Subscibed channels the same box appears on the bottom left of the screen with the words "skip 15 secs". The screen winds back for a second or less and the freezes.
Any help in resolving this would be greatly appreciated.
You can only rewind for as long as you've been watching the channel - it's just rewinding into the buffer that it had loaded. i.e. if you switch to a channel and watch for 5 minutes, you'll be able to rewind a maximum of 5 minutes.
