If only you could put as much effort into finding the answer rather than the question.
But you have a box presumably, so why not try it and see? Not that there is anything worthwhile to record on their Sport channels. Good luck recording Jake and Clare!
Does accurate recording work if the broadcaster
(a) changes the channel, eg, from BBC1 to BBC2,
(b) changes channel on the fly, eg, starts on BBC1 but ends on BBC2, or
(c) switches to the red button service (roughly equivalent to (b))?
Plus, my experience is that when there is a series that is spread over two channels, and that should record as a series, eg, F1, the series link fails. I have also had recordings fail on BBC1 because the programme was delayed. I don't see accurate recording as a panacea. So, given its failings on normal broadcasts, what chances are there of it working on IPTV?
PS The answer? 42. The question? Ah, that is a more difficult problem. I will have to think about it...
